Some type of explanation would be handy.

This webstart doesn't seem to want to work... Why don't You make an executable jar?

A curious idea, and it's kind-of interesting to watch the collisions, but the 'control' part seems to be missing. I jabbed at various keys and sometimes something seemed to happen at the beginning of a simulation, but I couldn't tell you what or why.

I don't understand how it fits in with the theme at all.

Technically interesting but I don't understand how that fits the theme... Hardly looks like a game really because i don't seem to be able to control anything :/

Ditto, not loading in Chrome, does load in Firefox. And... pretty as it is (I get what's going on - city's collide! Muaha! I recognized Manhatten, right?).

I got it to load in Firefox 4, but couldn't quite figure out how to control it. Pressing space and enter seems delayed, clicking doesn't seem to do anything really, might be due to the size of the datasets you're using. Anyway, fun example of 2D particle collision. However, it does seem slow given the small number of particles. If you use a quadtree or binning approach, you probably could bump it up to 20,000 or 30,000 particles, and with improved collision response. :)

Couldn't get this to work in IE or Chrome. Sorry.

Firefox 3.6 on Ubuntu with Sun JVM, worked fine here, but doesn't seem to be interactive beyond "press enter to advance". Is this a feature or a bug?

Neat tech demo.

Hmm, won't load in Chrome, Windows link seems to just go to the web version.

I couldn't really understand this, either...
Instructions related to the controls would be cool!
