Record of a speaker slowly moving

Awesome example of aliasing. Recording at 60 fps and playing a 61hz signal is causing the speaker to look like its wobbling at 1? hz. The deformation is cause by your camera sensor's data being read in a scan line fashion

If you wanna see your speakers move put on the song Stigma by Noisia: http://www.youtube.com/watch?v=Y8oRUQhDxU0

skip to around 2:55 and turn the volume up at 2:58 and watch your speakers dance :)
