So I spent most of this week working on this; a 'fake Christmas sweater' sweatshirt featuring Sierpinski's Triangle. As a Christmas tree. It's available in the US (sweatshirts and long-sleeve t-shirts) and in the UK (t-shirts). UK long-sleeve t-shirts will launch as soon as the sweatshirts tip (sell 5 shirts) because I want at least one of these campaigns to print!
