Very interesting things, in fact. And he'll sell many of them to you. I first came across this curious gent several months back when he was offering to take a picture of the sky above him and send it to you for $10. For $1 he would think about you for a minute and email you. He now offers all sorts of things on his website that you can buy. But far more interesting and poetic is the page he's set up on Tumblr. Here he comes up with an activity for each day. Even if you don't end up doing the activity, it's entertaining reading.
