Rorschach Ink Blot Masks
Would you like to cause your friend to take a great big turd in his shorts? These Rorschach masks, if I'm to believe what I'm seeing on the video, are built specifically to do just that. Made famous by Jackie Earle Haley playing Rorschach in the movie Watchmen, and based off of the Rorschach ink blot test, these masks are pretty brilliant. Warm breath fades the ink to transparent, and then cool air darkens it to produce a moving effect. And according to Rorschach maskermind (thank you) Grafixfan, the ink won't even kill you!
The fabric selected for the masks allows clear vision and breathing. Always a plus. They come in 5 different Rorschach ink blot variations.
