Infinite detail?

[MountainLabz]

it says on the front page, infinite detail with infinite size. where does the infinite detail come in? I can only zoom so far.
Perhaps I'm missing something.

You're missing that there's a parentheses with the word (almost). This app is more about the feel.

I have my own app which works similarly though I think I allow more zoom: https://github.com/Apostolique/Mitten. Eventually I'd want to support a canvas like in Endless Paper though I don't think it's completely trivial to code.
