I explored a couple other ideas and included them just to show my process.

My actual project proposal is to make an interactive lamp that requires a group of people to coordinate with each other. The lamp shade itself will be lasercut be on a vertical track. One person of the team controls the vertical height of the shade and the other, the brightness of the bulb.
The height of the shade will directly correspond with person A and how far away they are from the lamp. Similarly, person B will need to take their phone out and use their phone light to control the brightness of the bulb via photoresistor.
It requires the coordination of both parties to properly project shadows and silhouettes onto the table.
