The Colorsmith Graphical Worm is still going strong, but it needs more submissions. If you have an interest in messing around with Photoshop (or graphic software of your choice), please feel free to join in the fun!
Anyone can submit. The only real requirement is to fit your artwork into 600 pixels wide by 450 pixels high by 72ppi. For the sake of aesthetic and flow, try to match the artwork to the previous work in the project, and the way to make certain you 'lock in' your spot is to sign up on the forum.
