Triquid (trigonometric liquid)

#WCCChallenge Liquid 21.11.24

https://openprocessing.org/sketch/2460217/

This is a particular interval of the equation that 

I have already partially used in the sketch from 

which I made the "fork". 

This trigonometric equation also has other different 

and interesting intervals, but I highlight this one 

because it is very "fluid" ... or rather "liquid"
