Reliving your childhood…Spirograph

2 05 2010

Is there anything more satisfying than producing a perfect Spirograph?!!! Do you remember the frustration of getting half way through and then the little cog slipping off the big one?!!!

Well now you can relive the fun and get perfect Spirographs every time: http://www.benjoffe.com/code/toys/spirograph/.

Click the little cog icon on the top right hand side, adjust the settings then click it again and off you go! Email a copy of your best creations to yourfriendlymathstutor@googlemail.com and we’ll put a selection of the very best on our website!

If you are brave enough to look into the maths behind Spirograph (including hypocycloids!), check out: http://en.wikipedia.org/wiki/Spirograph

Have fun!
