Triskelion Blocks
Akihiro Matsuura, Hiroshi Shirane
A triskelion is an iconographic pattern that consists of three legs (or spirals) having three-fold rotational symmetry. We make use of this strange but intriguing figure as a motif of our new construction toy. We present two families of triskelion blocks with/without a central equilateral triangle, where one block is connected to another at its concave parts in three directions. Such connection with some tiling properties can be effectively used in constructing various shapes using the blocks. One can also enjoy “balancing play” of physically standing constructed shapes on the ground which reminds us of coordinated group gymnastics.
