Here's a comment from the author, and a conversation that explains how this was created: https://news.ycombinator.com/item?id=25192569

Not the creator, but this was created 13 years ago.

It seems like it is about 8 scenes that spawns the next scene in the vanishing point of the current scene.

If you click anywhere a sidebar appears where it says "An infinitely zooming painting created in 2007".
