Mail Me Art is a British-based project run by Darren Di Lieto. In the course of a year, Darren had artists, both professional and amateur, send him packages in the form of art. The tremendous variety of styles and media that were sent in is incredible - from postcards and envelopes to boxes and pieces of wood. You can preview some of them here.

Mail Me Art reminds me of the occasions when I would draw on envelopes for letters to friends. I knew another person who did the same to postcards and then just randomly pick a friend to send it to...usually someone who needed a boost. I've always thought it a fun way to share something nice, to spread our creativity, and to make the recipient's day.
