The TARDIS Prime design appears to be a pretty big hit. I can't say that anything else I've done has taken off and reached as many people as quickly as this has. And to such positive feedback!
The Doctor Who / Transformers mash-up t-shirt is being featured exclusively at GraphicLab [link] for $10 (+ shipping) and only until the end of Sunday. Tell your friends!
A huge thanks to everyone who has already purchased one!
