"Spiderweb"

A quick sketch I wrote which generates a dynamic "spiderweb" (so named by Ivan Moscovich in his "Big Book of Brain Games"). It is based on code from DevApprentice LLC (www.devapprentice.com/exspiderweb.htm), since I don't have that book.
The algorithm was designed to make still images with integer "skip" values. However, my sketch constantly redraws the spiderweb, using a float which is incremented by .01 each iteration. It seems to create an illusion of a moving tunnel or morphing sphere.

I revised the code a bit, reducing the number of math required per iteration. I also implemented a technique inspired by toxi - it now precalculates the values for sine and cosine.
On the other hand, the new version antialiases all drawn lines, which probably cancels out any speed improvements I made.
If you want a more precise picture, you can decrease the "step" variable. For more detailed pictures, increment the 100 in spiderWeb(value, 100);
