So I decided to make valentines for my colleagues and my students, and this year I decided to use my childhood Spirograph kit. I loved playing with this when I was in grade school myself. Watching the patterns appear as your pen goes around the spiral is a little bit like magic.
They don't always work out quite right. Every once in a while the pen slips. But overall, the patterns are really beautiful and fascinating.
If you've never used a Spirograph set before, it works like this:
After choosing one of the large rings and one of the small discs, the large ring is secured with tacks on top of the drawing paper (there's a base of thick cardboard underneath). The disc of choice can go either inside or outside the ring, and there are many small holes to choose from where you put your pen. After that, just roll around the ring until the design meets up with itself again.
You can also change pen color and new designs can be created by shifting to a different hole in the disc. All the holes on the rings and discs are numbered so if you make something really cool you can duplicate it again later.
After I doodled a whole bunch of different designs, I cut them out and glued them on to red paper, added a little greeting with a heart sticker, and voila' ~ fun, mathematical valentines were ready for delivery.

Wishing everyone a happy day of Saint Valentine!
