Seems like everyone’s been programming particles lately. I was reminded of some stuff I was doing in Java years ago, and realized that AS3 is now up to the challenge. So took an hour or so this afternoon and created a particle storm:

Just 1000 particles, two “suns”, and an applied blur each frame. An earlier version had 10,000 particles with no problem. It was just overkill here with the blur. I love what ActionScript has become.
