Paper arcade! If you build it, I will come.
I "toyed" with a much naughtier title to this post but went with the work save version.
If you can't be like my friend Tim Neuwerth and build your own Mame system, be a nerd and make one of these. Paper arcade is a small paper build it yourself arcade which features such great classics as "Pac-Man", "Defender", and "Guantlet". So what are you waiting for. Hook up that printer and warm up your thumbs, its foldin' time! Link
Ken won't disapprove of such a detailed toy-sized arcade, but barbie will probably guilt him for months until he finally sells it all at a garage sale at bargain prices and is left with nothing to show for it but a memory and a shell of the man he once was.
