I don’t think that works if the blocks are reflecting light rather than emitting it.
- csours 8y agoDon't worry we've already pivoted. We're no longer using concrete blocks, now it's giant LEDs.
- LanceH 8y agoUnfortunately we lost the entire first floor when we dropped a block and filled it in.

- kurthr 8y agoWell they could be transparent (Red/Green/Blue filter) glass blocks stacked in front of a reflective screen... One question is... visible from the sides, from above, or both?

- martalist 8y agoUse 4 colours then: cyan, magenta, yellow and black (CMYK, as used in print).
- dTal 8y agoWhy wouldn't it? Your eye does not know the provenance of the light that hits it. Red light is red light.
