LFSR & arduino: a subset in hardware

The Linear Feedback Shift Register might appear to be "random" but it is of course far from it. The first two words should make you suspicious of how random things are. Version 1 does the actual production on the arduino chip. I'm hoping to break out the logic onto the breadboard for a future version. The arduino would then be relegated to a provider of voltage and ground.

Since it is all rather predictable, it would be fun to have a second arduino with light sensors on it be able to come close to the existing model and then sync its own LFSR and output to the LFSR.
