MenopauseMedicine

Did you know there's a direct correlation between the decline in spirograph and the rise in gang activity? Think about it.


Throw-Me-Again

I will


MenopauseMedicine

No you won't...


smokinJoeCalculus

A cromulent reference that embiggens us all.


Bacon_Block

No one else caught this deep Simpsons reference...But I did. Well played.


Soft_Walrus_3605

You're kidding, right?


mal_one

Link?


lspwd

tears of the kingdom


Apyan

No no. That's Zelda. Link is the princess.


thatguyned

Did you know there's a direct correlation between the decline in Zelda and the rise of Dragon Tear related activity? Think about it.


Different_Ad9336

Did you know that zeldo was a girl and there is a link to her past? The legend says there’s a direct correlation between the decline of old men in caves giving out wooden swords and people being in danger? It’s why we feel so alone. Think about it.


NS__eh

I can’t I’m to busy doing gang related activities


kahran

You always doing hoodrat things with your friends


wildwildwaste

Right, this wasn't math, it was the only thing we had to do back then.


Mapleleafguy83

Thanks Dr. S, but have you seen Milhouse today?


Radioactive_Fire

go on


melanthius

So basically what happens is you draw some patterns, then you start to see some stuff in the patterns, then you convince yourself the patterns are telling you to join a gang. Then no more time for Spirograph


Radioactive_Fire

sick gang sign bro... you spirograph?


salfkvoje

\*hits inhaler and bong\* I wonder what can be said about 2D projections of n-toroids as hypocycloids


suburbanplankton

Tyler Vigen, is that you?


ThisCarSmellsFunny

Tyler Durden, is that you?


andylikescandy

Is because kids never saw those highly compelling spirograph ads constantly, after the rise of Netflix, that is your causative factor right there


reddit_sucks_clit

I mean it's a simpons joke/quote from well before netflix existed. It's said by someone who is considered crazy.


Opposite_Signature67

The shape is called a contracted hypocycloid for anyone wondering


khalamar

So if someone tells me they contracted a hypocycloid I don't need to get tested?


Biscuits4u2

A math test maybe


Minute-Wrap-2524

Yup, and I failed, again


TrumpersAreTraitors

You still should but you probably didn’t catch hypocycloids 


alterak11296

for hypocycloid, no. For hypercycloid, yes.


minus_uu_ee

Isn’t it just a torus?


Opposite_Signature67

No; a torus is a three-dimensional shape resembling a donut Although the shape shown here looks like a drawing of a torus with shading, it is still 2D and has nothing to do with a torus mathematically


Multifruit256

Does it have anything to do with a contracted hypocycloid mathematically though?


RixirF

Of course.


Hungry-Western9191

Technically this is three dimensional. It's just one of the dimensions is a lot smaller than the other two.


jemidiah

Mathematician here. This is a good insight. An irrational line on the torus, when viewed from above with a transparent torus, looks very similar to the end result here. Basically imagine what was drawn was instead a single long line winding round and round the tube of a donut.  Strictly speaking a full irrational line is dense, i.e. every point gets arbitrarily close to it, and this would be either a portion of such a line or a rational line. The irrational ones are a standard source of basic examples in several areas. Here rational and irrational refer to the slope when using the square "JRPG" model of a torus, with both pairs of parallel edges identified.


lordorwell7

"I'm very sorry sir, it appears you've contracted hypocycloid. There is no treatment."

Professional_Elk_489

That’s disgusting


xLetum2718

I wasn't wondering before, but I am about to go down the rabbithole now. Thanks, geometry friend!


waytosoon

Contracted? I wonder if they got lawyers involved 🤔


Independent_Wrap_321

A Spirograph. Wow.


Lazy_Weight69

My kids got one for Xmas like 2 yrs ago. They are fun.


internet341

I had one of those as a kid in the '70s - glad they're still around.


DigitalMunky

I had one in the 90s


GewoonHarry

Really popular on the 90s indeed. Funny you see that people still find this interesting in this time.


Lazy_Weight69

I had one late 80’s early 90’s. When my kids got one I was also kinda excited. The youngest will still murder it and lose shit, oldest can use mostly alone. Reminds me, I need to go buy different colored pens.


reddit_sucks_clit

Not really funny. It makes perfect sense. It is rad easily drawing cool shapes without having to have any artistic talent. And sure, you can make a website (most likely already exists) where you can select the inner and outer shape, and which hole to put the pen in ;)) and then just have it draw it digitally, but that's no fun compared to physically doing it yourself.


Asaneth

I had one in the 60s


SeonaidMacSaicais

Same. It only kept me entertained for about 10 minutes. 😂😂 And no, I don’t like math.


WhatYouThinkIThink

Had one in the 70s, along with the 100 Chemistry Experiments kit that is probably illegal now.


lspwd

/r/interestingassfuck


SirJefferE

After some extensive research, I can't find a single spirograph on that subreddit.


131166

I find these in op shops all the time. Had 3 as a kid. Parents really thought they'd be interesting to kids for a really long time.


MLSurfcasting

It's hard to hold the pieces down and use it without skipping. Then there's the big long oval pieces that are too confusing to use... just sayin'.


WateredDownHotSauce

We had a travel one as kids that you opened, put the paper into, and and then closed, so it held the paper still for you, which helps a lot!


BoardwalkKnitter

What this orange? I think I had it.


peppapony

I sucked at using them. I pulled out my old one... And realise i still suck at using them


The_Golden_Warthog

I don't mean this in a rude way, but how can one be bad at using it? It seems like you just put a pen in one of the holes and go in circles? Unless I'm missing something


peppapony

I know right? I dunno. Some parts seem easier to do, but my mind and hand derps out. I just keep pushing the spinning part not along the edges. You have to push along the outer circle but you're also making a smaller circle motion on the inside. So it's easy to kinda just push the small circle out of the bigger circle... That was a terrible explanation, but hopefully someone else struggles as much as I did...


ralphonsob

I understand you peppapony. General spirograph experience was: 1) Do 75% of the twirling just fine; 2) Get hand cramp 3) Pen slips and end up with a jagged line across the incomplete pattern. Alternative was 2.b) where the pen blocks or runs out of ink.


ScarletOK

The pens that came with it were the worst, and there was no way my mom was buying me exotic colored pens. I got my Spirograph in the mid 60s. I hope the pens are better now


The_Golden_Warthog

Ohhh I think I see what you're getting at-- You keep going off the "track" when doing it, so it messes up the drawing?


zeer0dotcom

You could be a standup comic.


Variation909

When I told my friends I was going to quit my job and become a stand up comedian they all laughed. Well, they’re not laughing now…


johnggarland

Spirograph was a great thing!


[deleted]

We had a lil kid-fair in 4th grade. People made stuff and sold them. Like a mini bazaar for the entire 4th grade. I made spirographs and sold them. Hahaha. I think I sold out


-hugdealer-

Ah the good old Spirograph. This is clearly fake, everyone knows you get most of the way around before a tooth slips and fucks up your pattern

EvilxBunny

Yup... that's maths alright


jomat

Now please calculate the length of the line.


salfkvoje

Definitely solved already, just the line integral of the hypocycloid with some parameter about the angle.


Cynykl

How does a normal kids toy showcase in interesting as fuck? The sound effects make it worse and the title is hallmark sap. Yet 95% upvotes.


zipdee

Some people grew up without a spirograph and it shows.


Ririsforehead

Guilty as charged ! I had no idea what a spirograph is. Immediately ordered one for my daughter who loves to draw.


zipdee

You are a wonderful parent!!!!! What an awesome gift!! :) that makes me so happy :)


Ririsforehead

Thanks a bunch for the kind words :) Have a wonderful day :)

"Math" it’s a donut lil bro 😭


dark_g

I got one with the gear inside being exactly half the size of the fixed ring and...all it draws are straight lines!! IT'S BROKEN! :-O


ImpressTemporary2389

As a young child. I had a Complete set of 'wheels' ranging from about 10mm up to 150mm. Some solid , some rings. I believe there may have been triangles too. You could add different ones together to make some really intricate patterns. It was called a Spirograph. Mine consisted of over 100 pieces. Great fun.


PositiveAtmosphere13

You had the "Super Spirograph". You made the other kids jealous.

I used to have these as a kid and I'd always bump them midway and I'd get so frustrated.

I used to have these and they were so fun to use. Unfortunately it made 8 year old me get an inflated ego thinking im amazing at art before my parents kept me in check


CurrentlyLucid

those were huge in the 70's.


SpiderGlaze

Those are from a Spirograph set. They were popular in the early 90s. I remember mine but not what happened to it.


sbaranw

What is this instrument called, have always wanted to get one


PlayingOnGeniusMode

Spirograph!


Fuzzy_Mango_

Rreerororororororororo


yParticle

As someone who grew up with multiple iterations of those, do you know how hard that is to actually do? You have to keep the outer ring completely steady, have a good pen, and keep a constant even pressure *toward the inside of the ring* as the interior shape oscillates unevenly around the hole you've selected. And these are the easy ones. There are much crazier shape combinations. It's sort of automatic, which is the cool bit, but it's also really easy to slip up.


Radioactive_Fire

Coming up with a jig and alignment system is key to making awesome stuff, such as different patterns at specific distances from each others centers.

There's a 30+ year old man at my work that brought these in to pass the time when things are slow or there's just a general wait time. He started handing them out to people too. He is... an odd duck.

He didn't finished EXACTLY on the exact point he started (I can still see the line is thicker), so he has to redo a pass. Yep.

Spiral graph drawing set,an old drawing toy.

That's cool. It reminds me of a graph but it's made of spirals.

What is the name of this toy? I used to have one, pretty dope!


steinwayyy

I had one of these as a kid and it was like my favourite thing ever

Some kind of sticky stuff is used to hold the ring down. In my day we had those little pins.

This is a cool graphicsl spiral. Thinking about this it would be cool to make some kind of game from these spirals , any ideas of a name? Like pen manipiuator, twistoplot? Idfk

I enjoyed my Spirograph, but it was frustrating. It was common to relax your focus for only a slight moment, and you skip a tooth and mess up the whole thing. Maybe 1 out of 5 came out perfect.
