hello guys, i got tired thinking by myself yesterday about this new software i found while im studying about pipelines. Gaffer - seems to have a houdini like structure to it. http://imageengine.github.io/gaffer/index.html
Narton - compositing application, looks alot like nuke.

yes, i could evaluate it and never talk about it in here, but it would be nice to hear from you guys.
