Silk is a fun site for creating digital art that I found out about from Larry Ferlazzo's excellent blog. All a user has to do is click and drag the mouse around the screen to create some cool looking designs. A person can change the color of their picture as well and no registration is needed. Once a picture is completed it can then be shared or emailed to others.
I recommend checking out Silk by clicking here!!!
