Those are all excellent examples of a big ole' projection TV in use in an arcade. The Tekken 4 cab is probably the closest to what I had in mind.
I think if I could build some kind of set of free standing controls like seen with the Tekken Cab, then I could integrate that with my TV.
That awesome rocking cab with the bench is pretty awesome too
I have seen those before, and that might not be a bad idea either, considering the monster size of this TV.
Specs and plans for any of these might help me decide which design to tackle.
