Wait . . . that's not it.

The ultimate goal is . . . a mechanically animated cab topper with the same dedicated theme as the video game inside the cab . . . but for today, we'll settle for annoying the card carrying purists. :duckhunt jk

Picture an animated (i.e. moving) toy from a pinball game sticking out through the top of a full-width, 6" tall(?) box on top of the cab.
- The front edge of the box is directly above the marquee.
- The box hides the animation mechanism and has paint or artwork related to the theme.

That could be interesting.
Any specific game ideas yet?

Yes, as implied earlier.

If anyone wants to play along just pick a game, figure out what motion you need to tell the story, and design the track.

For example, if you wanted a Super Mario Bros. theme:

- Put a horizontal pipe on the left and a vertical pipe on the right.

- Use one motor to drive two Goombas back and forth, one on each side of a 2 or 3 block high center wall.
-- Limit switches tell the controller to reverse the motor.

- Mario is on the lifting arm platform driven by a second motor moving slightly faster horizontally than the Goomba motor.
-- An open-top guide track for the first lifting arm bearing (yellow) has a few vertical "jumps", one of them so he clears the center wall, one so he jumps into the pipe on the right, and one or two more for fun.
-- Put a second bearing on the other side of the arm that is pushed up by an angled block that is part of the Goomba mount. Instead of running into the Goomba, Mario "jumps" it.

- When Mario gets to the right side and drops into the pipe, he falls down to the bottom, and continues to move to the right. Shortly after that, the platform hits a limit switch and the Mario motor reverses.

- As Mario moves all the way to the left, the bearing (yellow) passes under a 45 degree "trapdoor" (red) which falls down behind the bearing after it passes. Shortly after that, the platform hits a limit switch and the Mario motor reverses again.

- The bearing now rolls over the top of the 45 degree "trapdoor" and up until Mario exits the horizontal pipe, starting the cycle again.

Bonus points for adding relevant sound FX -- see WannabeJoy's project here for the board to use.

Double bonus points for getting Mario to punch a brick and have a coin pop up.

Super triple bonus points for adding a mech showing Mario running right-to-left through the underground with a guide track shaped like a wider, flatter, vertically-flipped hysteresis curve that slides the underground Mario an inch or two toward the back of the mech on the left end of the Mario motor travel so underground Mario is behind a wall as he moves to the right. Underground Mario is pushed toward the front of the mech as he reaches the right end of the Mario motor travel. As underground Mario travels left in front of the wall, the wall blocks the view of above-ground Mario as he also moves left. ;D

Nice first I'm seeing Peppers Ghost, (also eerily enough this reply was made when exactly 666 views were on the topic) I've heard of Ghost Peppers don't think my stomach can handle either of them.

Well... It's a secret to mostly everybody.
