It’s not officially licensed, but it’s as geeky as the ones that are:

This shirt was designed by Red Bubble seller Jimiyo. If you look closely though, you’ll see that it has one minor flaw: there are only five tile designs shown, even though a Rubik’s Cube is supposed to have six different tile colors or patterns. Maybe the sixth tile hasn’t been crafted yet.

It would also have been geekier if the shirt had been named Persson‘s Cube. You can get the Mine Cube t-shirt at Red Bubble for approx. $19 (USD). The shirt comes in a variety of colors. The design is also available as a sticker.
