Extreme Low-Fi stroboscopic demoscene effect (with paper)

This is a paper version of a double-wheel rotation, which used to be (still is?) popular in the demoscene back in the old days. ...Only it is paper, pop-up, and activated with my hands... and the effect may be... mmmh. slightly less efficient as i fail to reach stroboscopic effect (i doubt any human being would, given this design ;-) )
