From Goodinson Design:
Pixton is an online user-generated comic strip. Without having to draw, people of all ages can share their ideas, opinions, and stories publishing them instantly to a worldwide web audience.
An intuitive, contextual interface lets you build an episode quickly and easily, one scene at a time. Pixton characters are created by choosing from preset attributes and expressions, specifying hair and skin color, rotating body parts, and setting height and girth with a drag of the mouse.
You have the option of allowing others to remix an episode. Pixton creates a duplicate episode which can then be altered or added to, without affecting the original. Any remixes are listed below an original episode, allowing viewers to follow its evolution.
