Translucent plastic for lightshade?

[SciArtImages]

Just thinking aloud really, but wondered about trying to do lampshades with some of my images, I would do stained glass but one step at a time!
Does anyone have any knowledge of sources for a translucent plastic that could be dye subbed onto, either flexible enough to make a circular lampshade or rigid for square ones?
Or is a generic plastic of a certain type suitable?
Thanks in advance for ideas.

Be interested to hear about this as well. I had a trade customer looking to print his photos onto lampshades, not many options sround.
