This is probably my first digital art piece, created around 1999, when Lingo (Macromedia Director) was still popular.
Sphere traces particles that spin within a 3D sphere. Changing perspectives, positions, and speeds generate some interesting patterns.
Nostalgically, I include the shockwave applet also. I am not sure, however, if Adobe still offers shockwave plugin for free download.
Those were the days, my friends.
