How to use
Add nodes by clicking on “Add Node”.
Select a node by clicking on it and type on your keyboard to give it a title / rename it.
Link nodes by dragging “wires” out of the inlets / outlets and plug them into another nodes inlets / outlets (inspired from Blenders node based shading and compositing system).
You can only connect black with red / red with black. Black is inlet, red is outlet. You can not connect inlet with inlet or outlet with outlet.

You need Java 1.8 to run the builds.


  • Subtitles and image-import for each node
  • Seperately render UI from workspace
  • Database
  • Make workspace dragable / movable (like Google maps)
  • draw only when necessary (more events) (ditch Processing?)
  • Test if it runs on windows
  • Even more testing!

Pretty sure I’m gonna leave it as is for the time being though.
