  That was really cool. Tried to tap along and noted how my rythm increased, but changed how many taps per beat I did over time.

  I was going to say that this one (which sounds like a not that short loop) and the "fold4, wrap5" (which just sounds like a horrible short loop to me) didn't give me the same illusion, but then I listed to the one in the Wikipedia article again and it didn't work for me this time either (short loop). I think the Bach linked above broke the illusion for me or else it only works for a very limited time.
