live demonstration: show 4D hand-held / bottle with light bulb source. After it is demonstrated, hand it round, then continue on how to do this.

TO DO TO DO TO DOKann man da was highlighten beim erklären?now, we can add some blockers and modulate; the design you currently see. One deficit: the cones on the receiver surface do not stay below the lens, and do not have a precise overlap
This is what the 6D prototype looks like …
This is one of 49 “single pixel” blocks for the 6D display. It projects out different patterns according to the incident light illumination.To test it separately, we feed it with a special pattern
Luckily, we can add more lenses. This rotates the beam back, which makes it a translation operation.
