Well it being the fourth of July and all I thought I might ask? So what exactly is flint other than a stone I can clang together to generate a spark? Flint is also a particle engine created for actionscript 3 by Richard Lord. Which is really easy to use and is also compatible with many open source 3d engines like away3d or papervision3d so I recommend checking it out it can be useful for creating a variety of effects and is also fun to play around with. You can create all the firework effects you can think of also snow etc.. The flint library is also available in C# although I have not played with it but will look forward to doing so in the near future. I am also currently examining Particle Pusher that was created by converting the c++ library particlesystems This particle library was thoroughly optimized and looks very impressive it also uses Pixel Bender Filters as well. Anyway here is a ridiculously simple Sparkler. This is one of the examples that comes with Richard Lords libraries I have only made a few modifications. The point is if you needed to create a particle effect with actionscript you could do it quickly and easily. I am also curious to see if the Flint Library can’t be converted to be used in .Net 3.5 I will play around with it shortly. Here is a virtual sparkler in case you didn’t get to have one.

Our Fourth of July was pleasant we grilled out had some friends over and watched other people light fireworks off while we had steak / burgers / beer etc. It was fun we also played horse shoes.
