Looks to me like a good way to burn up rare cathode ray tubes. Maybe a switch could be incorporated to cut off the cathode current when you're not home?
I have a nice collection of DG7-32, 2AP1's and a couple dozen other CRT's ranging 1" diameter at about 5" diameter. Don't think I'll be making a clock out of any of them.

well when it does burn in you'll be able to use the clock without power and it will be right twice a day  :-DD

the software could gradually move the clock display around within the crt to reduce burn-in

In the CRT Clock Kickstarter, the PCB looks so ugly I cannot look at it. Why can't people stick to tracks with an angle of pi/4? Why have bunch of different angles... Can anybody explain?
