Not too many options (only BG color can be changed) but nice and simple, not really a complaint I hope. One thing I noticed after trying to figure this out for awhile is that there seems to be an error in kerning/spacing between sets of time displays; the seconds, further displayed into the thousandths it seems, overlap on every other set so as every two sets of time displays look like an even longer string of changing digits.

Although it delivers in the "cool" factor arena, its utility is further hindered by the speed of rotation—I couldn't really take a passing glance or even sit still for few moments and tell immediately what time it is—this, compounded with the spacing error noted above.

Thanks!
