Photojojo is one of my favorite photography resources on the Internet. Every now and then I get a great email from them with a cool idea for photographic projects, tips or general inspiration. And one of the more recent emails was all about photo projects for kids.
Face it, if your kid has a cell phone, then chances are he or she has a camera too (and if they don't, then they almost certainly have on one their cell phone). The photo ideas for kids from Photojojo include playing with perspective (as pictured) and my favorite, create a kind of photo time capsule for yourself.
Anyway, it's pretty cool. Check it out at Photojojo.com
