I often wished the arcade cabinet for the TMNT games looked like the Party Wagon, thought I would share my weird idea today. This design made more sense when 4-player cabinets were huge and had large CRT televisions inside, but you could put a driving cabinet inside to make this an actual vehicle of sorts (similar to this old design of mine).
The blast shield folds up to reveal the screen, controls, and marquee. Otherwise it would look like the Party Wagon is parked in your living room.
Tried my best to make it look built of plywood and t-molding, so I do feel this is a very plausible design. Hatchback struts would be needed to hold the blast shield up, and the wheels would need to come from a riding mower, methinks.
