I agree a smaller prototype is a good idea. Even the 4x4 video may be sufficient.I think the best advice at this point is for you to make a smaller prototype. Perhaps 6"x6". Some none commercial none production parts already been suggested:
-Arduino Uno (5 volt system, might not have enough pins, may need multiplexer), a cheap clone is about 9 dollars.
As I recall, the Arduino Uno has 14 I/O pins available. This would be sufficient for a 4x4, 5x5, or a 6x6 array, with a couple of pins left over for other inputs.
