SYNOPSIS hydrostat [--display host:display.screen] [--visual visual] [--window] [--root] [--window-id number] [--delay number] [--speed number] [--count number] [--head-radius number] [--tentacles number] [--thickness number] [--length number] [--gravity number] [--current number] [--friction number] [--no-pulse] [--wireframe] [--fps] DESCRIPTION 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. OPTIONS --visual visual Specify which visual to use.

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.
