We have just opened our own clothing shop with cool gear and now we want your help to make it even cooler! So if you feel like geeking out and spreading game development love, create a t-shirt modders would want to wear and win great prizes in return. Read on to participate and you may soon have a t-shirt you designed available for game developers to buy and wear.
Made with Paint.NET
I wanted to give an example of modding on the T-shirt, I think I may be partially insane...
[ADDED] Version 1.6
I still think your cluttering the back of it.
