We designed and built a proof of concept t-shirt design editor and released this to a few of our friends and colleagues to test the idea. We created a community on Spectrum and encouraged people to share their t-shirt designs. After a few chats with people the sentiment was generally that it's a cool idea. None of the t-shirt designs looked like anything people would buy or wear, however. It seemed that we would need a collection of designs for people to 'hack' on and customise.
