DESCRIPTION
Wiggly squid or jellyfish with many tentacles. A muscular hydrostat is
a biological structure used to move its host about, consisting of mus-
cles with no skeletal support. It performs its hydraulic movement with-
out fluid in a separate compartment, as in a hydrostatic skeleton.

Strength of gravity. 0 - 10.0. Default: 0.5.
-current number
Strength of current. 0.0 - 10.0. Default: 0.25.
-friction number
Coefficient of friction. 0.0 - 0.1. Default: 0.02.
-pulse | -no-pulse
Whether the squid should pulse. Default true.
-wireframe | -no-wireframe
Render in wireframe instead of solid.
-fps | -no-fps
Whether to show a frames-per-second display at the bottom of
the screen.
