We always envisioned the Binary Epoch Clock as being able to be more than just a simple clock. Along with adding a new, more readable, clock face and 1D pong to the official firmware since launch, here are some alternative firmwares that will make it more than just a clock:
EpochPOV: Turn your BEC into a fully functional Persistence of Vision display with 32 pixels of resolution. Fun for the whole family!
Proton Pack Power Meter: Not just firmware, but an adapter circuit board as well to make the BEC into a pulsing power meter for your Ghostbusters Proton Pack or just about anything else.
