I just found out about Ramen, an open-source, node-based compositing application today. It looks promising, if for no reason other than to get node-based workflows in the hands of more people.
I’ll have to give this a try tonight when I get home… Maybe. The only way to get the software is to download the source and compile it yourself. I’m pretty sure that means I’ll be messing around with installing dependencies for a while before I ever get to try it out.
If and when I get around to compiling, installing, and playing with this, I’ll post a review.
