I tried the demo, it's pretty neat how you can make the barrels tip over and shoot the spray cans and shoot out the light and they all behave realistically.
May I suggest though that you increase the gravity? It doesn't feel like 9.8 meters per second, stuff seems to move sluggishly.
After seeing this I'm considering adding an automatic "entityfade" type of thing to the shadow system to stop rendering shadows a certain distance from the camera automatically, and to fade them out in a nice way instead of just switching them off suddenly. However, there are a few issues with this. The most important one being that multiple cameras would pose a problem. One camera might be in a totally different part of the world than another and so only the shadows near the first would be displayed. This is not an easy problem to solve, though thankfully it would not affect many people.
