There's this old game called Miner 2049er that had radioactive creatures that glowed a lot like this. Of course that game was on the Atari 400, while this is easier on the eyes. I actually kind of like it, though obviously it's not general Flash Portal faire.
In that case, have you considered submitting to the Art Portal? You couldn't do this effect in a .jpeg (maybe a .gif but I'm not sure), but you seem to have some credible skill about you. It's also nice that you decided to submit something after two years.
Nice job. Don't be a stranger!
