A theorem walks into a bar...
The Klein Bottle is a mathematical joke: a surface with only one side. This one feels just right in your hand and opens bottles with ease and style. Built to last in steel, it's the perfect touch for any math fan's kitchen.

Yes, it really works!

Klein not-a-bottle-opener is here.

My case for Raspberry Pi computer. To be assembled with the "LED lightguide" model nr. 486757 (http://shpws.me/6yFP). This is the case everyone is talking about! ;) Features: snap-fit fixing system for the board, easy to mount/unmount; snap-fit closing system, no screw required; bottom holes for blocking the computer by screws (sliding mount); led lightguides (not included in this model, available here: http://shpws.me/6yFP ); pre-shaped hole for GPIO access, just cut it out to open. In this page you can find a gallery of shots working cases by enthusiast users! http://marcoalici.wordpress.com/raspberry-pi-case-gallery/

 Clothoid.B lamp is created by a mathematical curve formula and then that spline is lofted in 3d CAD software. Resulting form is parametric and adjustable in almost infinite number of combinations.

You can imagine this 3D form as afterimage of one single point in space as it moves, self-intersecting and rotating around, creating this 3D object. Whole shade form is actually one single line... wrapping around itself. Whole 3d printed light shade is created in one piece by Shapeways.

This lamp is available for purchase now on Shapeways. What you will get from Shapeways is 3D printed lamp shade only.
