For a mathematical art project, I want to animate the following pattern I made on desmos. It seems to be a Moire pattern. However I cannot make the pattern move smoothly and continuously because desmos lacks the computing power.



The pattern is a projection of several roating $3D$ structures mapped to $2D.$



Essentially I made the (moving) shadow of these rotating $3$-dimensional structures.



The pattern consists of:



$4$ boxes that differ by rotations.



I've defined the "waves" in the boxes on desmos with these equations:



$$ e^STlog(x)+e^STlog(y)=1. $$



$$ e^STlog(1-x)+e^STlog(y)=1 $$



$$ e^STlog(x)+e^STlog(1-y)=1 $$



$$ e^STlog(1-x)+e^STlog(1-y)=1, $$



Where $T$ is a continuous slider $Tin[0,1]$ representing the flow of mathematical time.



$S$ gauges the spacing of the curves. For pretty evenly spaced curves I used these $49$ values for $S:$



$$S=15.3039,10.3612,7.9153,6.3793,5.3019,4.4955,3.8656,3.3584,2.9405,2.5903,2.2926,2.0367,1.8146,1.6204,1.4496,1.2983,1.1638,1.04377,.93622,.83959,.75256,.67401,.603,.53871,.48045,.42762,.37969,.33619,.29673,.26094,.22852,.19917,.17265,.14874,.12722,.10791,.090664,.075316,.061733,.049793,.039383,.030399,.0227475,.0163414,.0111008,.0069525,.0038286,.0016664,.0004081. $$



So essentially there should be $2N$ fluctuating waves inside each box. $N$ waves are attached to the ends of the box $(0,0)$ and $(1,1)$ and the other $N$ are attached to $(0,1)$ and $(1,0).$ Each half of the waves are spaced evenly apart along the diagonals of the box.



In the images there are $392$ curves.



In the animation each of the waves should move at the same constant velocity as they propagate through the box.



The boxes could also rotate. That would be cool.



Requests:



$1)$ What mathematical tools could I use to analyze this moving pattern?



$2)$ Please animate this pattern.

    Nice pattern. I have taken the liberty to suppress the tag "harmonic functions" which is related to functions such that their laplacian is $0$ which a priori have not their place here.
