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. A creation of kaleidoscope innovator and artist Roy Cohen, and made from polished brass, cast acrylic, and colored glass. This item came to me in my Fall Curiosity Box subsciption: Get or give!

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? In the mathematician world, it is known as Spheroform It is the only three-dimensional shape that combines constant width and Tetrahedral Symmetry. Add To Cart.

The full details of the math in this process are described in this paper by Brand. Specular Hologram Knot: this complex 3D image is created by etched grooves that reflect a point source of light as glints, and each eye sees a slightly different pattern such that, via stereopsis, the shiny points appear to float above or below the surface.

Both Reuleaux tetrahedrons and revolved Reuleaux triangles present the same However the hat tiles the plane aperiodically- if one tries to shift a part of a hat tiling, the shifted part will not align or match up with any other part of the same tiling- all the way out to infinity! Skillfully printed in two colors by Brandon of Fractal Forest Makes. The easiest 3D shape to think of with constant width would be the sphere but here are a few more. This set is the creation of the folks at thecuriositybox and will be shipped out in the next subscription box in a few weeks. This beautiful design by Luycho uses both mirror anamorphic reflection and an accordion type lenticular dual image turning the plate degrees trades images. Add To Cart. I was inspired to Althogh the math says they can tile the plane, getting them to do so is more challenging than one might think! The ultimate expression of the Reuleaux shape creates the most sophisticated shape with a constant width. Here is a cool More information and Proof. These shapes have constant diameter no matter their orientation and will roll like spheres between two planes- note how the acrylic plate stays parallel to the table as the sphere and other orbiforms roll underneath. This item came to me in my Fall Curiosity Box subsciption: Get or give! The dodecahedron, with its 30 edges and 12 sides, is the basis of this puzzle sculpture.

If you place a book on top of multiple of them, the book will stay perfectly flat while rolling around. 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. What is so special about the Ultimate Solid of Constant Width? The one that resembles a pyramid is the Meissner tetrahedron, which is conjectured to be the orbiform of least volume. I uploaded two variations of the Meissner object, Type 1 has the 3 altered edges share a common vertex. I personally am a little obsessed with them right now; they are super satisfying to mess around with. Solids of Constant Width youmagine This shape is made using a triangle, however, it can roll like exactly like a ball. Mirror Anamorphosis: perspective often depends on the lens or in this case, mirror that is looked through. This d1-d10 dice set will be part of the very next Curiosity Box: Get or give! Solids of constant width!!! More information and Proof. Lady Liberty is revealed by bending the flexible Mylar mirror in to a half cylinder.
