I do imagine it would make for some intersting creations... I do believe however that you should need to modify the dye to make staining paint. This yields stained glass and the possibility of builing true chapels.
Gah yes, I saw the same post right after I hit submit. Unfortunately I can't delete my own posts, otherwise I would've avoided looking like a complete dink.
What about applying dyes to glass to get tinted blocks and/or light?
I support.
