Grand Illusions is a web store packed with all sorts of deceptive novelties, plus an online toy museum and gallery.
Here's a video about Its' Nuts featuring Tim Rowett, an extraordinary toy collector who had purchased a copy of the toy directly from me last year at the International Puzzle Party 32 in Washington, DC.
Puzzle designer Evgeniy Grigoriev created his own version, which he titled the Incredible Screw. Grigoriev is famous for his twisty-cube puzzles, and twice set the record for building the World's Smallest Rubik's Cube. On his version, notice how the nuts move at different rates when he turns the bolt!
