@Paul: Heh, I didn’t think about that. But yeah, any color combination would be fine. You could also use dim red and bright red as long as there is enough difference between them to be able to tell the dots apart in a dark room. :)

colour combinations reminds me of having my eyes tested. Perhaps issues with red/green colour blindness. Would suggest a range of blue/red and blue/yellow combinations. Would be great to see these at trainstations and airports. LOL

I never thought I’d hear the words “binary clock” and “functional” in the same sentence… well, without the “not” of course :)

Yes, you are right. It is 50 seconds and not 40. Good catch!

I was just checking if you guys are paying attention. ;)

Ether I can’t read binary clocks either or you can’t, because it looks like that clock is reading 1:11 and 50 seconds, not 40…

I keep thinking about getting a binary clock, but perhaps I’ll wait to find one of your design. :)
