Mood Rings and Hypercolor

I woke up this morning and went to grab a shirt off my floor to wear, and then I decided to get a clean shirt from my closet. My choice for the day? My Hypercolor t-shirt a buddy of mine gave me a few years ago.
I got to thinking about Hypercolor shirts and mood rings, whether or not they could be considered interactive clothing and accessories. I think they are. I mean, they are constantly changing colors and that's why people wear them - so their bodies can interact with the objects and change the colors. I don't know exactly what you could do with this kind of stuff to make a cool interactive art piece out of, but I'm definitely going to think about it. The first idea that pops into my head is having a time lapse video of a group of people with Hypercolor shirts on and watching the changing colors in a sort of morphing mosaic video...? Maybe? I don't know, but I think a time lapse thing would be the way to go here to see how the colors change over a long period of time, but in a sped up video.
