Do you like to play games with dice? Do you find yourself unannoyed with QR codes? Then we have the dice for you! Until you memorize which pattern is which digit, this is guaranteed to require a cameraphone to decode what number you rolled!

Please note that this is a proof-of-concept and a work in progress. OpenSCAD is not properly extruding my QR code line art, which leaves bad QR codes on the faces.

I ended up rewriting the whole thing, using a Ruby script to generate the QR code "pixels", then outputting OpenSCAD cube primitives for each "pixel." This works around the problem with OpenSCAD messing up the vector images. The updated version is "Useless Dice" to at http://www.thingiverse.com/thing:22997

NOTE: THIS IS A WORK IN PROGRESS. Currently, OpenSCAD mangles the QR code dxf images when extruding, so the results are similar to, but not quite, QR codes.

If you have a single-color printer:

• Print the core in a light color
• Get some modeling clay (e.g. Fimo) in a dark color and jam it into the holes
• Optionally, finish it with something like clear nail polish remover when dry

If you have a dualstruder printer:

• Load both models, printing the core in a light color and the pips in a dark color
