HTML5 Canvas + JS Fireworks

I'm no physics expert, but it seems like in real life the take off velocity is stronger at first and gets lower the higher it goes instead of vise versa like it is here. It gets faster the higher it goes instead of slower. Shouldn't it be the other way around?<p>But this is pretty cool regardless.

This is great. Best canvas fireworks I've seen so far! I was thinking of building something like it for a while... The last particle engine type thing I built was with the old DirectX 7 back in day (well maybe 10 years ago). Just out of interest, how much time did it take you to build this demo? (assuming the author is around)

Interesting. But this type of fireworks are mortars, not rockets, and thus should just follow a ballistic trajectory (i.e. add gravity plz).

Reminds me a bit of "Parcycle" - the canvas particle effect thing I made a while ago: <a href="http://mrspeaker.net/dev/parcycle/" rel="nofollow">http://mrspeaker.net/dev/parcycle/</a>

Very cool... but 10-12 FPS is disappointing.
