Here is a fun geeky accessory for all the Portal fans out there, the Portal Weighted Companion Cube Cufflinks.

These fun cufflinks are made by the same person that brought us the cool handmade Stormtrooper cufflinks last week, they are handmade from polymer clay and would make a great addition to any geeks wardrobe.

If you want a set they are available for $27 from The Clay Collection.
