That's cool man. I think I'm actually the odd man out here as I have no intention of writing any flash. I've never done a bit of flash before, but have a good understanding of .Net and all the environment resources at my disposal so I went with that. The LEDWiz interface is a wrapper around the .dll provided by GroovyGameGear. Yes, this all pretty much ties me to a windows pc, but I have plenty of those laying around and so far it runs pretty well on an old one.
I'm all for sharing resources. My code, all the images, and sounds are up on github. That's where I'll push all the development - more for my own personal organization than anything else.
It occurs to me now that folks might not be able to compile it, so I can make an .exe available for anyone that wants to see it. It works with a keyboard similar to how your flash program does.
