This program works well in Firefox 3 and Safari 3.1.2. It works very well in Safari 4, by which I mean the current WebKit nightlies. (If you're frustrated that the version of Safari in the iPhone has no SVG support, join the club.) In Opera 9.5.2 the program runs slowly (roughly ¼ the speed of Safari 3.1.2) and with stuttering motion. Firefox 2 is much worse; it works, but too slowly to be worthwhile. However, if your browser is running this program well, you can open it in a separate window and scale it to arbitrarily large sizes. (Or not.)
Any easily suggestible people who find themselves hypnotized, are hereby ordered to think for themselves, and to demand rigorous logic from any idea, internal or external. Everyone else may quack like a duck ... you know, if that seems like a good idea.
