moire machine/sketch.js

+//this sketch was used to program varying radial moires. Though I cannot figure out the parameters I used for the take in the edit, I provide the program for how these effects were created. Over the course of the projects production I would experiment and record many different versions of these radial moires and picked the best ones for the final edit of th project.
+
+//combining each layer of ellipses and adjusting their parameters many moire effects can be created.

+////-----------moire that uses a modulo to change it's iterations, thus it has a 'snapping back' quality to it's movement
