Art accessibility concept

Since my coloring pages are only lineart, it would be pretty simple to mat prints and go over the lines with puffy shirt paint. If I let it dry, it would conceivably preserve the raised paint lines, and allow blind people to feel how the art looks, to a certain extent.

Not something I currently have the technology to share via the internet, but definitely an idea. I may have to try it out with one or two pics at AI.

Input welcome, natch.
