Taking picture of a spinning propeller may produce unexpected results. See here: http://goo.gl/GeVJOp,http://goo.gl/IPeMss,http://goo.gl/tHkSoa and http://goo.gl/vQuc7Q. The mysterious photographs are a side effect of a digital camera that captures snapshots line-by-line. Depending on the speeds of propeller's rotation and camera scanning it is possible to generate various patterns. This animation recreates a few of them.HQ original: http://www.youtube.com/watch?v=H-nSL1_PwYIContact me at: yamabiko@abv.bgTwitter: x_YAMABIKO_x
