There's something about cubes. MC Escher loved them. Every nerd in the 80s loved his or her Rubik's Cube. In this stylish T-shirt, cascading boxes express infinity and the natural laws of the universe while giving Tux a very cozy place to rest. Showcase your love of free software and geometry while wearing this subtle expression of Linux. In Blue with the Linux.com logo (and full length Tux) on the sleeve. 100% organic cotton and fair-trade and ethically-sourced, too!
