V idlescale

Name: v_idlescale
Default value: "0"
Flags:

This variable controls the amount that the screen should sway automatically.
When this variable is set to a value above "0" the screen will start swaying in
all directions, similar as if the player was drunk of had a concussion. If you
want to have some real fun, set this variable to a value of "100" and run around
some maps. The larger the value for this variable the more the screen will sway
from side to side.
0 = Disable automatic swaying.
