I'm pretty sure that's a telescoping tower. You can see several layers of sponsor signboards behind the one with 279 on it. I can't see where the wires and tubing are coiled up, though. The two pneumatics in front would cause the cradle to move, to pick up the ball.

Is the light blue thing in back, possibly made out of pool noodle, a device to kick the ball out of the cradle? Or maybe to knock a ball off the Overpass?

I look forward to seeing this in competition. I still have fond memories of your unique tetra handling.
