2-digit geek clock

I am still not sure what project to use my rgb 7-segment display for. There were some very interesting ideas posted to the Hackaday forum. I like matthiasrs idea most: A 2-digit clock, using the red LEDs for hours, the green ones for minutes and the blue ones for seconds.

In order to get a better idea, rather then implementing it in hardware I wrote a little simulation as Java applet. Have a look and see how hard or easy it is to identify the time :-)

    Very cool!

    However, I think the colors change too quickly to read when the seconds are included.

    If you just select the hours and minutes, then the clock is easy to read and tell the time.

    Good luck!
