Just a neat little tech demo - the controls themselves don't support 60hz.

  The trick is that they aren't conventional adder modules. Each module outputs the XOR and carry (AND + red shift) for all 30 bits at once. This is done recursively until one of the results is 0 - the other result is the sum. This adder can actually work perfectly fine for most 27-bit inputs, but it breaks down if a carry bit is propagated more than 16 times.

  Impressive. I can't even fathom how it works with only a single AND and a single XOR gate per full-adder. Yet. Maybe I'm missing something?
