The Paintshop . biz aka Paintshop Factory
The Paintshop is a real time collaborative painting tool offering you the possibility to sell you artworks and buy great pieces of art for a very afforadble price.
As you paint onto the canvas, you also see other people paint. The painting can at any time be claimed by one of the painters, who then becomes the owner of the piece. Once a painting is claimed, it's up for sale in the gallery in an edition of one. When the painting is sold, it's shipped to the buyer printed on canvas and the money is split between the owner and the gallery (the Paintshop) (minus production costs). The price of each painting is calculated based on a combination of aspects, including title, author's popularity, complexity and time-investment.
