ShopMyApp is a prototyping solution intended for designers that allows a Photoshop file to be exported as an interactive device prototype.

Part of the solution is a Photoshop plugin that exports a PSD as a texturemap and JSON-formatted metada about dimensions and texture coordinates. This is pretty cool from general perspective and might have other uses also.
The exporter is free to use so feel free to try it at http://shopmyapp.com. Also the question we had in mind was if you see any potential in this kind of thing. Like if we'd develop it to certain direction, could it be something to pay for?
