The 3d screen is projected into the air with a flashlight mounted on the back magnet

 The 3d screen is projected into the air with a flashlight mounted on the back magnet. I have a flashlight headlight that creates a focused light, not parallel light like a regular flashlight. The electromagnet draws closer and farther away from the bulb to create a converging dot near and far into the air. in order not to create straight light streaks but spread out the flashlight phase to converge so that each pixel converges light. Create small flashlights like dot image to 3d screen
