KToon, is a new 2D animation toolkit created by Toonka Films and now made available as a free GPL'ed option to the 2D animation industry. KToon has been developed using OpenGL from the Qt library and follows the same interface style of commercial products such as Macromedia Flash (TM) and ToonBoom (TM). Currently KToon is still in beta and only has 2 modules (Illustration and Animation), but it already allows one to export animations to the SWF format. Screenshots are available. Developers and testers are welcome! Read More
