You will check your monitor first
That is the reaction, every time. The page leans about a degree and a half and nothing else changes, so your brain blames the screen, the desk, your neck, and only then the page. It is a small joke that lands because it is small.

Askew and tilt are the same thing

The loud one from the same batch is do a barrel roll, which spins and lands upright. This one leans and stays there.
Askew gravity
People ask for the combination often enough that it is worth having. Tilt the page, then let go of the floor, and everything slides off the slope into the low corner. It is a mash-up of this and google gravity rather than anything search ever shipped.
