I'm not sure how this is a 1-bit interface. It seems like it's '1 bit per minute'. If you arbitrarily choose a unit to use 1-bit to realize, you can build almost anything. For example even the highest end '24-bit' ADC and DAC chips around are often 1-bit supersampling (sigma-delta) architectures. You can communicate through human speech with a 1-bit interface, for some definition of a 1-bit interface. I'd also add that random combinations of flashing lights is horrible from a UX standpoint, anyone tried programming a universal remote that only communicates via flashing lights?
