there have been a lot of threads on this theme, pinball manufacturers should listen up.

Far as layout, I'd be ok with a couple spinner discs in the middle ALA whirlwind that looks like a turntable (cept the discs would have to scratch back and forth), and then maybe an intergalctic robot that wiggles.. an off-ramp that says "brooklyn exit", maybe a "lookin down the barrel of a gun" captive ball. maybe some gold chains hanging over a ball lock lane?
