I had a spiragraph kit.
It was actually annoyingly difficult to make any remotely interesting
images. I thing the felt pens we used were just too blunt. Also very
hard to make the gears rotate without slipping off. Or ripping the
paper. Or the template sliding. Or...
I was just looking at a site explaining how to build one, and I suddenly
had a killer flash of inspiration: THERMAL PAPER and a LASER POINTING
DEVICE!
Think about it - 100% friction-free graphing! EPIC WIN!!!
I want to try this *so* badly right now...
