Draw Island is a nice new (beta) site for drawing online. This is one of the better digital art sites to come around in awhile. It has a very nice user interface, lots of draw tools to choose from, and the ability create custom animations. Also, there are lots of features to come, such as sharing to your favorite social network site as well as mobility (ie, iPhone).
I highly recommend checking out Draw Island by clicking here!!!
