Rynprov - you really want an alarm? To be set in hextime? You're even more of a geek than me!!
I'll look into it - but just don't ask me to build in a conversion tool so that you can figure out what 6:45am is in hextime - you're on your own with that one! (It's 9am hextime actually - given my current rules, but this will change using Tilmans info below)

Tilman - I see what you mean. I was assuming that a fourth (third) hand would be needed for the maximes - e.g. a normal clock has hours, minutes, and seconds - so 3 hands, whereas the hex clock would have hours, maximes, minutes, and seconds - so 4 hands. What you are saying is that although maximes and minutes require 2 units on a digital clock face, they are combined into a single hand on an analogue version...

I'll give it a go... watch this space.

It's kinda cool. But I have some suggestions: Would you add an alarm feature and a digital time readout on the clock face?

No. For an analogue hexadecimal clock two hands are usual:

The short hand turns once a day, the long hand 16 times a day.

If a third hand is used, it´s 16 times faster than the long hand. It makes 256 ticks in one circle, and thus one tick every hexadecimal second. That´s already the fourth digit - a fourh hand would be useless.

(What you wrote would be true, if every hand made only 16 big ticks in one circle. But that would be very strange.) Greetings...

By the way: http://en.wikipedia.org/wiki/Hexadecimal_time

Tilman - I never even knew there was such a thing in reality - it was just a bit of fun. According to the URL you provided, to display hex time on an analogue clock face would require a 4th hand for the maximes, so it's probably more suited to a 'digital' type display, but I'll consider giving it a go...
