The trouble with paying for textures in this case is that the Cyclorama itself only cost $10-or-so on sale. Since I generally refuse to pay more for add-ons than the cost of the original figure, they'd have to be damn good textures, there'd have to be a lot of them, and they'd have to be real cheap. It's easy enough to make my own in Bryce & Photoshop, or from pd photographs, or whatever. Which is not to say you shouldn't try marketing some textures; I think a lot of people bought the thing and are waiting for a chance to use it.
