Drew’s Fourth Dimension app has such a brilliant logo, I just had to have it on a T-shirt. Now you can have one too! We’re picky about our T-shirts, so we made this one exactly what we’d want to wear ourselves. It’s printed in a four-color process with a soft white ink underlayer, which gives a good balance of image quality and detail, while still looking and feeling good on a black shirt. There’s no text or other clutter, just the 4D glasses image, which speaks for itself. Enjoy!
Certified math nut Sondra Eklund has made an awesome sweater. Before you read her explanation, take a look at it and see if you can figure out how it works.
Of course, the synesthete in me says her color choices are all wrong. But she’s coloring a different animal here (primes, not numerals) so there’s no real way to be “right”. Regardless, I want this as a T-shirt!
