/* DOOM Fire Eye

 Slightly modified to polar coords by Jason Coon
 Video demo here: https://twitter.com/jasoncoon_/status/1567672583436247046

 Updated 2D Fire effect, with "enhanced" dragon's breath mode. 
 Now with More, Better fire!  Version 2 has more dramatic flame,
 and an improved wind algorithm. 
 
 The method is inspired by the low-res fire in the prehistoric PSX port of DOOM!

 *  Evil Eye 2D - 9/7/2022
 *  Jason Coon (Evil Genius Labs)
 *  Video demo: https://twitter.com/jasoncoon_/status/1567671615214731264
 * 
 *  Slight modification of Blinky Eyes 2D - 6/5/2022
 *  Debra Ansell (GeekMomProjects)
 * 
 *  Simple code to display 1 blinking eye on an LED matrix. Tested on a Lux Lavalier (40mm Fibonacci64 Micro).
 *  Fine tuning variable values for the best look will likely depend a lot

// Beating heart pattern. The heart shape is formed by a square turned 45 degees to form a \"diamond\" which is
// the base of the heart. Two semi-circles connect to the upper two sides of the \"diamond\" for the rounded heart
// portion. Depending on your resolution, you may want to play with the anti-aliasing distance to improve the 
// definition and appearance of the heart's outline.

// Ratio of the height of the heart to the length of one side of the diamond inside it
// length of one side of the diamond is also the diameter of the circle
var ratio = (0.5 + 3*sqrt(2)/4)
