I decided to switch up my project idea. My last one was too educational and not very artistic. I still want to do something with projectors however I want to make them more interactive. Research to follow. The content will be time lapses probably Reno or Nature time lapses with interactive animations that grow over the looping lapses.
Ideas for message: humans have a profound affect on nature, places in Reno that could be better, etc.
Human interaction both good and bad.
Research on interactive projection:
Eyecon: Software that uses a camera feed to draw interactive areas that then trigger something else. http://www.frieder-weiss.de/eyecon/buying.html
PoMotion: Can use any sensor. http://www.po-motion.com/
