Download of Nodes 2.0.4 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This software for Mac OS X is an intellectual property of Yanobox.
The application lies within Design & Photo Tools, more precisely 3D Modeling. According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software.
From the developer:
Nodes offers unprecedented power to create connected motion graphics and abstract particle universes. Nodes is used by leading artists to create high-end screen graphics in motion pictures like The Avengers, Planet of the Apes and Ender's Game.
Start out with primitives, 3D models or footage to create a point cloud. Then populate the animation with text and manage connections dynamically.
You may want to check out more software for Mac, such as PatterNodes, MindNode Pro or Synpathy, which might be similar to Nodes.
