UV Sensitive ABS 3D Printing Filament

This is quite a unique type of filament I'm not sure what the exact application would be for using this, but I'm sure there is something. It's a UV Sensitive ABS 3D Printing Filament, which turns a reddish pink color almost instantly when placed in UV light (The sun). Once it is taken out of UV light it will change back to the cloudy white/clear color within a couple of minutes. This filament is sold by Makergeeks for $19.95 per 1/4 pound spool. Check it out, and watch the video below:

They have those shirts that do this. I'm sure someone will come up with a crazy idea to use this stuff for. Maybe logos on bathing shorts, or surf boards, or parts of a car?

Here's another video I saw on this stuff. At least I think it's the same stuff. Pretty cool filament :)
