Developer Lost Marble Software has released Moho 2.6, a 2D cartoon-animation system.
The Mac OS X-compatible application can output to video, or for streaming over the Web with Macromedia's Flash SWF.
Moho is vector-based, and works with scanned drawings. It's also suitable for illustration tasks. Animation tools include skeleton manipulators.
Moho 2.6 imports Adobe Illustrator and PostScript files. A demo is available from the Lost Marble Web site. The demo watermarks final images and movies with a demo label, and exported Flash animations only appear in greyscale. It costs $99, no UK pricing is available.
