Overview
Wiggly squid or jellyfish with many tentacles. A muscular hydrostat is a biological structure used to move its host about, consisting of muscles with no skeletal support. It performs its hydraulic movement without fluid in a separate compartment, as in a hydrostatic skeleton.

-
--root -
Draw on the root window.
-
--window-id number -
Draw on the specified window.
-
--delay number -
Per-frame delay, in microseconds. Default: 20000 (0.02 seconds).
-
--speed number -
Animation speed. 2.0 means twice as fast, 0.5 means half as fast.
-
--count number -
Number of squid. 1 - 100. Default: 10.
-
--head-radius number -
Head size. 10 - 100. Default: 60.
-
--tentacles number -
Number of tentacles. 3 - 100. Default: 40.
-
--thickness number -
Thickness of tentacles. 3 - 40. Default: 18.
-
--length number -
Length of tentacles. 10 - 150. Default: 70.
-
--gravity number -
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.
