This totally-not-a-joke Atom package indents the selected text in Fibonacci style, i.e. the zeroth line is indented by 0 spaces, first line by 1 space, the second line by 1 space, the third line by 2 spaces, the fourth by 3 spaces, the fifth by 5 spaces, and you get the point. This package only indents the first 20 lines of the selection because Fibonacci numbers can get really large really quickly.
You can also keybinding ctrl-alt-cmd-i to Fibonacci indent your document in real time!
WARNING: Python support is still in beta.
