Swapping helices is a mechanism that may be considered mathematical art. Five helical parts are locked together, forming a rectangle floded around a cylinder at an angle. Each of the five parts can slide independently. When the top part is slid down, it connects from the other side and becomes the bottom part. So the helices can change order while still remaining connected.
Please order a 3D-printed do-it-yourself parts kit from iMaterialise at this page (check with Oskar about dye and assembly), or contact Oskar directly if you are interested in obtaining a fully colored and assembled sample of this math art.
