Definitely worthy of further research  The weirdest result i had was the light bulb in the ceiling started resonating at quiet a high pitch, i don't know why it did that it was incandescent 60W If that was the small pic controller i built be carefull the PCB layout was hard to get going and wrongly layed out, i remember doing some serious track relaying under the 7seg displays, although if you follow the circuit diagram that was good The controller above was much better but more expensive due to the 4 delay chips used, that LTC chip oscillator caused me headaches i could not find math routines that were fast enough, if i remember i had to do 24 decimal place maths but luckily the pic has real fast BCD add and subtracts so i rolled my own long decimal divide and multiplication routines in assembly which were much faster than C or any other floating point routines i could find in assembly. Because all the maths was done in Binary Coded Decimal it was a breeze to display  without the needed floating point to ASCII conversion. I don't even know if my eyes are good enough to hand build it now that LTC was a bitch to hand solder, 8 pins and very small package.
