Detect Rotation — Several times in the last 2 weeks, I’ve wanted to be able to put a circular “puck” down on the table and rotate it (like a knob) to adjust some object-specific settings. But sadly, this feature will not be available until the second generation of PlayTable.

Detect Glide —I want the table to be able to detect an object I slide across the digital surface. More specifically, I want a gui to be able to perfectly follow a sliding object and update in real time.

Detect Height — It would be really interesting to be able to stack special cubes on top of one another, and on top of the playtable, that would send messages downward to the playtable, about how high the stack is…
