I know some people prefer video but I strongly prefer text and examples.
Feel free to add video as well, - just wanted you to know at least some of us where happy :-)
If the video intrigues me then I invest time in setting it up and reading the documentation.
Then maybe i'll install the software, then i'll go to the tutorials (in that order).
Right now think about Luna like about a new programming language with rich, visual representation and a very limited set of available libraries. If you are processing data that could be visualized or you are inspecting data, looking for the best way to modify / understand it - Luna could be the tool you are looking for.
I strongly encourage you to play with Luna, see example demo scenes and try to create something from your field of expertise. We would love to help you do it! Use our chat / forum if you have questions / problems. I would be more than happy to later create a video showing your system in work to demonstrate what Luna is suitable for! :)
What do you think about it? :)
The real-time speed probably doesn't make for a nice animation but it would definitely be easier to follow.
