W00t! These guys used a killer laser galvo system to play MAME arcade games not on your VGA monitor, not on your TV, but on your wall! Apparently there is an add on to the regular MAME32 that will output vector values for use with vector monitors. As I guess vector monitors were in short supply they used lasers. The laser control system was not scratch built (darn!) and they didn’t build the lasers either (crap!) so to do this yourself I’d guess that your going to have to spend some bucks. But hey, the final result is oh soooo sweeet!
