Inspired by the USGS's Sam Droege (the man behind monitorchange.org), we're starting another project to turn park visitors into a remote sensor network! It's simple: Put up a sign asking people to set their cameras or phones in an angle bracket, take a photo, and post it with a hashtag to Twitter, Instagram, or Flickr. Then we harvest the photos and create timelapse views of change over time.
Check out our Instructable with details on making the signs and running the software to get your slideshows up and runnning.
We'll have three signs installed at Maker Faire 2014 on May 16, 17, and 18 in San Mateo. Get ready for lots of makers running around!
