Square Dance is a playful variation to the Turn Four puzzle, proposed by Sjaak Griffioen. Sjaak's idea was to add some lego dolls onto the squares, and have them dance. The object of the puzzle is to scramble it by turning groups of four randomly. Then the puzzle should be solved again, with all lego dolls in a square, facing the same direction, and alternatingly male and female.

Buy at https://i.materialise.com/en/shop/item/fractional-gears or at https://www.shapeways.com/product/AC524R66H/fractional-gears Fractional Gears is a gear set that features a gear with half-fold rotational symmetry. A gear with 180-degrees symmetry is said to have two-fold rotational symmetry. The green egg-shaped gear has 360-degrees one-fold symmetry. For a 360-degrees turn of the green egg-shaped gear, the smaller red gear rotates by 720 degrees. Following the earlier naming logic, this gear has half-fold rotational symmetry. In order to make the cardioid-like gearing, the red gear has two layers. The teeth pattern continues from the bottom layer to the top and back to the bottom. In order to fit the bigger red bottom, the green gear has a cut out to make things fit. Copyright (c) 2023, M. Oskar van Deventer.
