Everyone blames the screen first
A degree and a half is enough to look wrong and not enough to look deliberate, so the first reaction is always to check the monitor, then the desk, then your own head. Only after that does anyone consider the page.
Drag anywhere on it here and the whole thing pivots to follow your hand, which real search will not do. Search only leans one way and only that far.
Two names, one rotation
Askew and tilt are identical. Google askew, google tilt, tilt google, the askew trick, all the same single line of styling from 2011. It was cheap to keep so it stayed live while the seasonal features got pulled.
The loud one from the same batch is do a barrel roll, which spins and lands upright. This one leans and stays.
Askew gravity
Enough people ask for the combination that it may as well exist. Lean the page hard, then cut the floor, and everything slides down the slope and stacks in the low corner. It is google gravity on a hill rather than anything search ever shipped.
