The puzzle is how a mark of single turn helix on the wobbling magnet appears as double turn helix to eye and to camera under day lighting. Actually this exact apperance do not change with horizontal view angle tested about 45 degrees of difference. Mark appears as a ghost image with low contast. It also not clear how the mark can appears at all while the magnet is spinning. (note the day light condition) First image is the magnet with mark standing on the table and the second is the puzzling apperance while the stack of four magnets vibrating in nearly circular motion at 120 Hz and spinning at 60 Hz under base magnet spinning at 120 Hz. This combination generally produce a single cusped/noded epicyloidal patterns shown on some latest videos on playlist. https://drive.google.com/file/d/0BzJym-YfdQbccW8td1M4aXQ5TjA/view?usp=docslist_api https://drive.google.com/file/d/0BzJym-YfdQbcRnJka0tnYVpLZ3c/view?usp=docslist_api
