I'm super excited to announce monthly catonmat geek t-shirts in collaboration with Teespring! Every month on the first Monday, I'll be launching a Teespring shirt campaign with an awesome geek tee.

Teespring is basically a Kickstarter for t-shirts. If enough people commit to buying a shirt, everyone gets their shirt. Otherwise nobody gets a shirt (and nobody gets charged).

This month I'm presenting the limited-edition HTML5 tees. This shirt is also the official tee of the HTML5 Dev Conf that's taking place in SF on October 15 & 16.

This shirt is designed by my co-founder SubStack and it's available on American Apparel and Hanes tees.

Update: Sold out and no longer available.

Grab it and see you next month!
