Tunnelscope Circular Reflection Kaleidoscope: in this novel design a straight length of transparent acrylic rod provides the reflective surface, and two wheels filled with resin and interesting shapes of colored glass can each be turned separately to produce a flow of psychedelic patterns.

Solids of constant width to visualize cool properties of mathematics and geometry. This is a collection of 8 different solids of constant width. Included models are Meissner tetrahedron, revolved Reuleaux triangle, revolved pentagon, revolved heptagon, and four more. All models are made to be the same scale Higher infill or wall Summary This are 5 solids of constant width, split in half for better printing results.

The ultimate expression of the Reuleaux shape creates the most sophisticated shape with a constant width. Few surfaces keep their width while rotating on any axis; we're used to seeing this characteristic in spheres. But as incredible as it may sound, other shapes with the same property aren't circular, such as The Solid of Constant Width. Leonhard Euler discovered that the Reuleaux triangle always maintains the same width. Four spheres with equal radii, placed at the corners of a regular tetrahedron, form a three-dimensional version of the Reuleaux triangle but without the constant width. Then, Dan Bergerud replaced the tetrahedron's edges with a group of spheres touching the edges, creating a solid object with similar symmetry and constant width, the Ultimate Solid of Constant Width. In the mathematician world, it is known as Spheroform. It is the only three-dimensional shape that combines constant width and Tetrahedral Symmetry. It conveys the knowledge of one century of discovers and mathematical analysis to find the right equation that creates this shape,. What is so special about the Ultimate Solid of Constant Width?

The intricate patterns seen come from shiny trinkets that flow in oil, and two mirrors that are precisely aligned at a 60 degree angle to produce the sixfold symmetry. The easiest 3D shape to think of with constant width would be the sphere but here are a few more.

There are other shapes that are capable of rolling as freely as spheres do. Zac Eichelberger, a mechanical engineer and design enthusiast demonstrated FOUR of them at work in tandem. The Reuleaux Polygons set comes with four incredibly intriguing solids of the same width, machined out of solid copper. Precision-made to be the exact same width, these tabletop toys are baffling and at the same time enjoyable, as you roll them around your desk while marveling the absurdity and awesomeness of geometry the same way Leonardo Da Vinci did when he discovered constant-width solids in the s, or Franz Reuleaux when he began exploring them and their applications in the s. The Reuleaux Polygons Collection makes a great tabletop accessory for anyone who loves math, geometry, design, and engineering. The four polished solids make for a great anxiety-busting toy, even more so when you place a plane on top of them to see how they roll perfectly without any change in their width! Yeah, science! This mathematical collection showcases the evolution of Reuleaux Polygons. The Reuleaux Polygons set comes with four intriguing solids of the same width, machined out of solid copper.
