Ceiling robot

Ceiling tiles weigh about 2.75 lbs. I could do something great if I could automatically raise one and lower something through the gap. A disco ball and speaker would be simple and great, or a nerf/ping-pong-ball turret. It might be easier to remove the edges from a tile and mount it to the bottom of the bot so that it can raise or lower itself and the tile looks right when the robot is fully raised.
