I made this having been inspired by the recent Doctor Who episode Vincent and the Doctor. And no...I didn't repaint a masterpiece. I'm using a photograph of the original here, and did my best to digitally reproduce Vincent Van Gogh's technique on the Time and Relative Dimensions In Space machine.
T-shirts, iPad covers, prints, etc...over here.
UPDATE: I have been forced to update this image, linking to a heavily watermarked image and taking out any links to larger versions. Someone is on ETSY selling this image on products as if it were theirs. I also saw a merchant at Gallifrey One selling small prints of this work. Live and learn.
