What you are watching are the spiky pulsations of iron dust stimulated by computer-synchronized electromagnets. The electromagnets which are underneath the platform create magnetic fields that are turned on and off in time with the song. The effect is pretty cool and amusingly enough it reminds of the motions in the video "Around the World" by Daft Punk.
