Can this shape tile the plane? It is not easy to guess by just putting the shapes together. With a little thought however there is an easy proof. It can't. How far can it go though? How many rings of tiles can you build around a first one. This is called the Heesch number of the tiling.

These are pendants that I hope to deliver to a friend in the hospital. The files are designed in Open Office, exported as jpegs, and then imported to Cut Studio which can be used to drive both the vinyl cutter and the laser cutter.

The 4x4x6 cuboid was first built by Tony Fisher from a regular Rubik's 4x4x4 in 2004. Joshua Bell commissioned the design of an open source 4x4x6 design in 2011.

The design for this puzzle is really quite complex and the supplied STL files are probably only printable on high-end printers such as Shapeways' SLS printers. Nevertheless, I hope the SolidWorks file will still be useful to many for learning the art of puzzle design or making derived puzzles.

Saw this sign in a show called Morel Orel. It was on the door to his dad's study.

I found it funny, hope a few others will also. There are also a few other signs like this in the show . I will add them when I can.

Size is 100mm x 100mm

This is an hexagonally-tessellating lizard tile closely based on M.C. Escher's famous design. This vector art has lived on my old personal homepage, since 2008, at

Recently, Angus Hines (http://angushines.com) downloaded it and used it to lasercut a bunch of ~3" tiles in fluorescent acrylic (which are shown in the attached images), and it occurred to me it was probably time to share these files on Thingiverse.

Update 2011-12-15: Angus just sent me these photos of some lizards printed on FDM/FFF equipment, and I've uploaded them, as well as the .STL and .CDR files he sent along with. Thanks, Angus!

This is the Snowman by ChristineBowyer except I added the following:
//this will flatten the object for dxf export
//comment out if you want 3D
projection(cut = false)

This allows you to export as a DXF file. If you want the version with thickness comment that line out.
