Lissajous figures
I used the trig functions to draw Lissajous figures. When I was a child I enjoyed making Lissajous figures on my oscilloscope—now you can have the fun with Scratch.

Jens suggested making a "pendulum in the sand" version of the program. This would be a simple remix of the Lissajous figures, since all that is needed is to "damp" the oscillator, making the amplitude of the oscillations get smaller over time. The damping could be different for x and y.
Rather than do this myself, I offer it as a challenge for the intermediate scratchers.
Post your remixes on this thread, and add them to the Math Projects gallery

Re: Lissajous figures
Great project, Kevin. People might also be interested in the fact that the MIT Lincoln Laboratory logo is just such a figure: http://www.ll.mit.edu/about/lissajous.html
P.S.: Being from the Salem area, I like to think of them as Bowditch Curves
