> *The Bouncing Node was one of the first nodes we developed for Nodalin. It demonstrates a few basic behaviors and properties, works on its own, and responds to the rendering dimensions. With the ability to accept other Source nodes and adjustable properties, it showcases Nodalin’s approach to modularity, ease of use, and composable node design.*
