There are many other Binary Clocks available but do you find yourself somewhat perturbed by the fact these clocks aren't truly binary? They may look binary and count up in binary but they still have decimal digits and only represent those digits in binary not the whole thing.
This clock is different though, this clock shows the time as the number of seconds since the day began - truly binary.

Yes Yes, new version will be coming soon with goodies such as choosing how 'binary' you want your clock to be, help to decipher the time and widgets of course.
