I had a friend once whose nickname was Linky. Anyway, here are some cool things I've stumbled across in my web browsing today...
My Kid Took These photographs taken by a 3 year old
Catherine's Animals portraits of animals against interesting backgrounds (I think my favourite is Owl 1, or maybe the porcupine, or maybe armadillo 1...)
Multicolr Search Lab lets you choose colours from a palette and then will search Flikr for photos that include those colours - a different way to see how colours work (or don't) with each other
Yeondoo Jung an artist turning children's drawings into reality (I'd seen it before, but it's really cool)
Garfield minus Garfield self explantory really
