I've got some OpenCanvas 1.1.b72 .wpe event files that I wouldn't mind sharing in addition to my 3d stuff. They're pretty neat if you have OpenCanvas because you can replay the creative process involved in making the drawing and it's not just the end result .jpg. (Could be great for general drawing technique tuts and the like.)
Various places have the older versions of OpenCanvas for free, including the Warpaint project (www.warpaint.se). The newest version (4.??.?) is a commercial product, and might be worth getting for producing comic style type art. Even on the older free versions, the toolsets and tablet response are nice - and the replay/recording of .wpe files is priceless.
Anyhow, is there a chance that .wpe files could be posted under a 2D category with any associated .jpgs of the finished drawing?
