I wanted to share another small web-world demonstration in Whalesong.

Try this in Google Chrome:


Source code:


What makes this program interesting is that I really am only touching
the left and top css attributes on each clock tick, as opposed to
redrawing the whole scene (as would be demanded in a regular world
program).  Inspect Element in Chrome should bear this out.

I should probably call this program "fruit-flies".  In any event, this
works on Chrome, but I haven't been able to successfully make it run
under other browsers.  I've heard that it works in Safari 5.1 as well.
