So...it detects a specific pattern in front of my webcam and draws an animation over it? And the animation reacts to me blowing into a microphone? I don't know, I didn't find this that exciting; a bit disappointing given the title. Maybe I'm missing something. Also, FYI: If you want to try it without wasting paper/ink, I was able to play with it by putting the PDF with the pattern to one side of my screen and using my iPhone's screen to reflect it to my webcam.
