Houdini is a a high-end 3d VFX application suite. Without a commercial license Houdini runs in 'apprentice' mode which allows to try out all features and learn the program. This ebuild was created & is used at Rising Sun Pictures, Australia. We use Houdini among other packages to do VFX work, currently for "Superman Returns" and "Charlotte's Web".
Hmmm? I can't see any ebuild.
