Conic Sections with Laser
Ellipse, parabola, hyperbolic branch, or hyperbolic arm: Cross-sections of a plane through a geometric body. In this case, a cone. A laser beam circling the…
Conway Cube
Test your spatial imagination. Assemble nine pieces to form a cube. Three 1x1x1 cubes and six 2x2x1 cuboids. It seems simple, what the renowned British…
Do they fit in the Box?
Too big. Or is it? The cube fits into the glass cube. Clear enough. But the pyramid, the star-shaped object? Too big. Some objects appear larger than they…
Quasi-Crystals
Golden rhombohedra. When correctly assembled, the various bodies (cubes stretched along their diagonals and cubes compressed along their diagonals) form a…
Rhombo Puzzle
Rhombo-dodecahedron from parallelepipeds. Twelve building blocks (each consisting of two connected parallelepipeds) can be assembled to form a…
Rocking Roller - the Oloid
Wobbles, but goes straight. The oloid has only one surface. It is the only known shape that fully unwinds as it rolls. This means that every point on its…
Tetrahedron Puzzle I
Three-sided pyramid, puzzle with two pieces. Spatial imagination is required: when correctly combined, these two equally sized bodies form a…
Tetrahedron Puzzle III
This puzzle game is mainly about spatial imagination. Four (2 equal) bodies made of spheres are to be assembled to form a tetrahedron.
Thread Models
Straight threads, curved surfaces. Rotatable cylindrical model: a cylinder becomes a hyperboloid. A surface generated by the rotation of a hyperbola. Movable…
Weird Wheels
Not round, but it rolls round. These discs aren’t round, but when they roll, their axis stays at the same height: solids of constant width. Disc-shaped bodies…
