I participated in a collaboration last month to create a whole bunch of drawings of a guy's son, Jacob. He contacted a bunch of artists on reddit.comand commissioned them to choose a photo from a gallery of pictures of his son and do whatever they liked.
After all the drawings were done, he printed, framed, and hung the pictures on the wall and revealed them to his wife as a birthday gift. She was blown away.
Here is the reveal video: https://www.youtube.com/watch?v=MzGcBPb_Y1A
Here are all the other pictures included on the wall:http://imgur.com/a/YmoqO#0
And the Reddit thread where he explains his story:http://www.reddit.com/r/videos/comments/2lfc2w/i_commissioned_23_rredditgetsdrawn_artists_for_my/clu8h05
