Whilst doing a search around ebay I can across this seller:
They sell prints of home made CGi images based on Star Wars, Star trek, etc. And they are really bad. I know they are only 4 or 5 quid a print, but who on earth would buy one of these images. They are very badly done using some really basic models. The backgrounds look like they have been created by a novice in Bryce 3D or similar.
Good luck to the seller. I would love to know if they have actually sold any.
