From the creator of the well-known GLaDOS ring comes a brand new accessory that is sure to be turning heads of those who see it - the Companion Cube storage box!

If you are a Portal geek like me - you know that the Companion Cube is basically a loveable version of Aperture Science Weighted Storage Cube. So if it's a storage cube - why not store something in it!
This little buddy is perfect for stashing your favorite pice(s) of jewelry or other small nick-knacks in style. Maybe it could even become a box for an engagement ring...?

The cube's corners reach up to nearly 1cm in thickness and the walls are as thick as ~4mm, so you are guaranteed that the cube will withstand rough conditions!
\ The actual product may not look like in the presented pictures - it comes in a single color, depending on the material you've chosen from the material list to the right! If you select durable plastic material, it is perfect for painting if you so desire :)

All gears are connected: turning any one of them will cause the rest to spin!

Nice little top, I bought mine in Stailless steel.  It can spin 30+ seconds, but the plastic one will most likely spin less.   

This is a model used to test printing detail of various materials. To see a detailed key and a high resolution example printed in Stainless Steel, visit http://www.thefrankes.com/wp/?p=2138. This object is tiny and includes many details in the 0.0 to 1.0mm range; it many not print in all materials, but I've made it available in all in case you want to try.

Cooksey Maze is a maze concept invented by an Englishman named "Mr. Richard Cooksey" in the 1970's. An evolved metal+plastic version with springs and pins was prototyped by Pentangle, but it was never taken in production. Oskar has been trying to locate Cooksey for quite some time, as the original "Cooksey Cilinder" has been an inspiration for many of Oskar's puzzle designs. This is a modified version of the original Cooksey Cylinder with a much simplified mechanism.

Earn a free Cooksey Maze if you can bring Oskar in contact with the original inventor of this maze concept. We know nothing more than his name, the fact that he is an Englishman, and that he already was an adult in the 1970's. Also the people who operated Pentangle in the 1970's do not have more identifying information.

This is a set of 10 poker chips all the same design. It's priced better per piece than getting them as singles because of the up front design costs of a co-creator model.
