Nerd Merch

Programmers like their nerdy stuff - shirts, mugs, stickers, whatever - highlighting their skills and favorite technologies.

Possibly the best source for things like that is Redbubble who have a huge selection of designs from thousands of designers, printed to order on a wide range of products.

Here we have a selection of designs for Python and JavaScript programmers. They are shown here on clothing but are also available on mugs, phone cases, stickers etc..
