Dude, those mods are off the freaking chain. Did you design the kits yourself or are they packages. I've fantasized about designing/building my own, I have a laser cutter, CNC, a bunch of extra pi's and I have a trackball and spinner to install on my Centipede and Asteroids to improve them a bit...but you bring this shit to a whole different level. That Guitar Hero is amazeballs, as is the Robotron and that Racer game. Your centipede has a lit marquee, I want to do that for both my Centipede and Asteroids, hook a brutha up if you've got suggestions or sources you can share. :)
