I was (again) thinking of methods for creating a cool DDP-like beam effect and ended up whipping up a silly little game not long after. :) I knocked it out in one night (tonight, actually), and it shows as it's easily my simplest game yet. There's basically no graphics to speak of, just blow up things with a giant rainbow laser beam of death. ENJOY.
As for other games, I'm waiting on a video converter box for my laptop so I can record footage via an external device (DVD/VCR etc.) without the messiness involved with direct screen capturing making things far more frustrating than they need to be. I plan to do one long demo reel with pretty much everything.
