The segments of the display are multiplexed, that is, they are being rapidly cycled such that only a few segments are actually lit at any one time. This all happens so quickly that it's hardly noticeable unless you point a camera at it or move your head or the clock.
The reason they are multiplexed is to reduce power consumption. If they were all lit at once, the clock would require a much bigger power supply, increasing weight, cost and power consumption. LED multiplexing is common practice.
Look at the clock with the naked eye at night and whip your head back and forth. You will see that the LEDs aren't on all the time. I used to see the vertical retrace of CRT's and TVs that way. Vacuum Fluorescent displays also flicker like this too. And by the way, that wavy line on an oscilloscope is not a line...it's a dot thats going from left to right over and over very fast. CRT might be dying out, but the DLP and OLED displays flicker too, just slightly faster than you can see.
a) only one segment of the LED display is actually on, confusing the crap out of the image stabilization algorithm in the camera.
b) reality is not what it appears to be. Things only exist when they're observed, and observing things through a camera like this, confusing the crap out of reality.
It's simple the refresh rate of the camera and the frequencies the clock use. Simple Electronic ^^

looks like some digital manipulation with a video editing program to me :D good job

One of two things:
a) only one segment of the LED display is actually on, confusing the crap out of the image stabilization algorithm in the camera.
b) reality is not what it appears to be. Things only exist when they're observed, and observing things through a camera like this, confusing the crap out of reality.

What Camera did you use to record this?

I don't remember. I used a camcorder I borrowed from my college's library.

I think it has something to do the fact that those red LEDs are actually blinking. I don't know why they all aren't the same.

i think it has something with polarity to do?.. but.. i'm not sure:S?
Great movie by the way ;)
