Homemade CRT Scope Clock

More information about my scope clock can be seen here: http://www.derivedlogic.com/Scope%20Clock/scopeclock.html .

This is my homemade cathode ray tube scope clock. It is ran by an ATmega168 @8Mhz, AD7302 DAC, DS1307 real time clock, and DS32Khz txco. The RTC keeps time while the clock is off and the time is automatically restored when switched on. The screen shifting after the minute increments is the screen saver. Timesetting is easy... one button to select the number to change (underline) and the other to advance the number.

Do you think you could run complex video through that? It would be interesting to see, kinda like the old 1920's tv's :)
