Ever roll a die and just KNOW the answer in advance? This die is a foregone conclusion. It''s based on the unistable polyhedron from http://mathw...

Have to find a good size. This is a solid version.This one is way too small. The numbers are unreadable.(Get one of the hollow versions I have; I...

A small, plain sphericon. It's a wee little thing, maybe the size of a marble, and it rolls in a straight line like one too, but not in a straight...

Created per a user request for a copy of the badge from the old NeXT machines.

Another in the "open" series, the numbers are on small triangles inside the larger "cage."

Johannes Kepler thought he had hit upon a secret of the universe, a demonstration of the guiding hand of God (and geometry) in the structure of the...

Not a reasonable die, but hey, Rhombic Hexecontahedron don''t need no reason.Very cool-looking, but also very sharp at the corners! Be careful.

Another "open" d12, with recessed sub-faces like rotated main faces. This one is based on the rhombic dodecahedron instead of the regular dodecahe...

Doubling cube? Up to 64 isn't high enough! OK, you don't really roll a doubling cube, and so it starts from 2 instead of 1, and so on. But anywa...

First attempt at a dreidel, ordinary Hebrew letters, etc.

Wondering about the details, etc... Maybe things should be different. Four dice, color-coded to tell them apart easily (most of the time). One di...

Boy Surface, in my favorite projection. It's in a network form, partly to cut down on volume but also because the whole point is to be able to see...

Trying some more designs for dice now. This is a regular wireframe dodecahedron with smaller, rotated pentagons inset in each face with the number...

Rolls like a sphericon, without all the volume, so it can be bigger. Reasonably sturdy, with internal struts to hold things together.Interesting: ...

These are not *quite* surfaces of constant width, but at this scale, the error is insignificant. If all goes well, these should be just 6mm across...

Ever roll a die and just KNOW the answer in advance? This die is a foregone conclusion.  It's in the shape of a flattened spheroid with a sing...

Based on a space-filling dodecahedron. Slightly irregular; I would expect it's probably not exactly fair.

A strip of material 10cm long, with a group of 5 pips and the number "5" indented into it 10 times, at each depth from .1mm to 1mm. To get a feel ...

Chainmail made of little carrick mats (technically 3x4 Turks-Heads) instead of rings. Each one links to four others, forming a somewhat stiff mail...

Chain mail... but different. The links are "trefoil" knots--ordinary overhand knots, with the ends joined. Because of the configuration of the kn...

A spiky sphericon-based d20. The outer spikes define the shape of the die by their convex hull, while the inner spikes carry the numbers. It migh...
