Here's the early version of my SpiroGraph applet. Check back periodically for updates!

To use the spirograph, click a color box and then click a pen hole on one of the disks. You can use multiple pens and colors at once. If you stop the drawing you can restart it with or without clearing it. You can change the pen colors or select a new disk when the drawing is stopped. Note that when you change disks or click the one (in the disk selection pane) that was being used in the drawing, it will rotate to match the one in the drawing. This is not really a bug - I noticed it but decided that it was helpful, so I left it alone.

I've gotten two reports of the controls not displaying with the Java plug-in. I'll look into this next chance I get.

Feel free to send me your comments. Enjoy!
