Aaaand it just reminded me of a balancing bird toy I used to play with all the time as a kid that also works somewhat the same way, but the bird also relys on a weight to help balance http://demoroom.physics.ncsu.edu/html/demos/533.html
it reminds me of this bar trick that works under the same principle. http://www.youtube.com/watch?v=P3qMA3vVTpI
So my guess would be that the curve in the shape above where the belt rests makes the belt lean towards you which puts the center of balance back at the tip of the swami where you hold it at. Very neat trick
