This is a simple imitation of https://www.instagram.com/p/BosaT7iAJwA/. (This composition uses gradient noise for the line's path, instead of the original's second-order pendulum.)
When rendering images/textures at small sizes, a well-known problem in computer graphics is that they may not look right. While our eyes and brain perceive colors blending together as objects get farther away, an image run through a typical scaling algorithm can end up looking grainy.
There are various techniques (including mipmapping) to address this problem, with various tradeoffs in CPU, GPU, and memory usage. For this feature request, we would select a technique whose tradeoffs work well with Vuo's realtime image processing.
