This is a true binary clock, far geekier than those things that show the hour and the minutes as separate binary numbers.
This one shows the number of minutes since 12:00 (noon or midnight) as single binary number.
The low 5 bits are in the inner ring; the high 5 bits are in the outer ring.
In each ring, the lowest significant bit is at the upper right, and significance increases clockwise.
So, in the image above, the time is 5:41.
(It is possible to configure the clock to show the time in text as well.)
The colors used to indicate 0 and 1 are configurable; there are a couple of flat color choices, a few based on gems, and simple black-and-white to accommodate colorblindness.
1.1.1 alows you to make the clock smaller.
1.1 fixes a bug where the clock would stop ticking.
1.0.2 fixes a bug.
1.0.1 fixes a bug where the text display of, say, 12:15 would appear as 0:15.
