As part of a unit on Pop Art, we created this Andy Warhol style pop art wall for our hallway using the free CamWow app. Each student in the elementary school took a picture of themselves using the front facing camera on an iPod. They selected which filter in CamWow they wanted to use for their photo.
This is a great activity for Open House at school! It created a kind of "Where's Waldo?" wall where students could bring their parents to search for their photos and their friends.
To print the images, I connected the iPods to my laptop and downloaded them all into iPhoto. I was able to select all the photos and print them off in sheets with 9 photos per sheet. I glued the sheets onto a long strip of paper before hanging in the hallway.
