As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I've been developing apps and frameworks for several years (since I was in college). Pre-Vuo projects include Kineme Quartz Composer plugins, iOS apps for education, an app that analyzes photographs of tomato slices, and software to help people with disabilities use talking keyboards.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.
Here's a composition that gives the illusion of objects endlessly moving back to front and gradually changing color as they do so. Actually it's 8 objects that each repeatedly slide forward 1 z-coordinate and then jump back to where they started.
Here's a composition. The idea is to make straight stripes with Make Stripe Image, wrap the stripes around into a circle with Pixellate Image Radially, and mess with the stripes' width using Ripple Image Radially.
I was going to suggest Tile 3D Object (like in File > Open Example > Scene > Tile Starfield), but that repeats one object (or set of objects) and it sounds like you want some kind of continually changing objects. Could you explain what you mean by things being changed per iteration over time? Or post a video of the "Iterator front to back" example if convenient.
