Looks great!

This kind of generative art is, I think, one of the best "non-productive" things that computers have enabled.

Two extremely minor nitpicks -

* When browsing through scenes, I notice that a title subtly fades in and out in the lower left corner. I missed this for the first several scenes, and then would often miss it when hitting a new scene, and I'd wonder what the scene was called.

* The "gallery" menu to choose scenes isn't in the upper-left nav, but rather, the hamburger menu. Before trying it out, I expected that clicking on it would take me away from the graphics, and show me a gallery of other projects.
