Armenian spinning top Quiz

Let's get dangerous! (c)

I'll try to send (or give, or whatever) an Armenian spinning top to the person who gives the best explanation of the difference between the left and right pictures.

I solemnly swear that both pictures were done with the same camera, at the same place, the same spinning top.

Let's set deadline for explanations as 13.00 MSK, 13 Jul 2000 + 2*13.
