yeah, ive been looking into this since the girlie said she would love a pinball machine/arcade cabinet.
they have some cool setups with a widescreen tv horizontally as the table and a square monitor as the table 'head' built into a cabinet.
+ an x-fire arcade stick and you're good to go.
edit* just thinking this + that 3d headtracking tech would be well cool. when you bobbed your head the table would move accordingly. it would work easy too wouldnt it.
