Here is another fun site to browse through. It's an initiative which uses standard mail as its medium. Some beautiful work has been created. The founders have also made it into a contest, and will be holding an exhibition in London later this year. Here's a description from their site:
"MAiLmeART.com was created by Darren Di Lieto, the founder and editor of LCSV4, after toying with the idea of doing a collaborative project that everyone involved in gets something out of. MAiLmeART is a little project designed to test your skills, make you some money and give you the chance to have a bit of fun. Oh!.. and win some really cool prizes.
In 18-24 months MAiLmeART will be holding an exhibition in London (venue to be confirmed). The show will include submissions from you guys and girls which will be on sale at the exhibition. The creators of items that sell at the show will receive 70% of the price their creations sell for, less the landlord’s cut. I can only offer 70% because I need to cover costs. The project will carry on and continue after the show with possibly another show the year after and the year after that. Hopefully the first show will be the first of many."
