Over Christmas, I added a couple of t-shirt designs to my Spreadshirt shop. Unlike prior designs, which primarily depict characters from imaginary children’s books and/or 16th-Century debates about the nature of free will, the new designs are depictions of famous paradoxes: the “devil’s tuning fork” and the Russell set. If you’d like one of these designs on a product that’s not yet available, let me know and I’ll cons it up for you.
