Cool. Is data encoded only only by color? +1
@the_new_powder99999 - Yes, but it might reflect but that will only increase the chances of the antenna receiving the signal, as it only needs just to be received, doesnt matter how many times. And the sender doesnt have to be working all the time, because a 29-bit instruction for a... moving bot for example is more than enough for several moves or operations, until then, the sender will be ready for another transmission.
This is really impressive!
+1 but i still like BRAY moar.
The problem with this is that any reflective surfaces will cause the signals to be recieved multiple times. It might be possible to get around this by making the photons move much quicker, but it is difficult to get them moving fast enough without huge gravity or gaps in the signal.
