I'm nearly complete with my Virtual Arcade cabinet... it's all painted and needs some final touches like T-molding and the custom marquee.
But, when I'm not home, I am now beginning to plan my virtual pinball machine, with a LCD flat panel displaying 3D pinball games, and the backlight LCD displaying the matching score boards and DMD graphics.
There are some kits available at Virtuapin.net from the basic wood boxes, to the full kit, all ready to bolt-together-n-go.
The front end is Hyperpin
Lots of forums and downloadable tables at VPForums and PinSimDB
