That's how I did this video, with an earlier, lower-resolution camera:

That's some weird compression artifact that causes that strange black
stripey stuff in the prop disk.

Slow frame rate, I think. The camera that took the video on my original movie
is low resolution and only has about 10 frames per second. The new one is
nearly full NTSC resolution with 27 FPS. Same manufacturer, just ~2 years'
improvement in technology (the cameras both sold for about $90.

As Andy noted, even the new camera's sampling rate of the focal plane tends to
show the propeller of the Boredom Fighter as an arc. Certainly not as bad as
the rising/falling ~ of the old camera, but still noticeable.

I just too cheap to spend money for a real video camera, that's all. :-)
