Hi, yall! I’m new to this but I thought I’d try to put Typst through its paces a bit and this is what I came up with. Takes several seconds to render for me, but beats drawing it by hand. 
#let pagewidth = 11 // in
#let pageheight = 8.5 // in
#set page(
width: pagewidth * 1in,
height: pageheight *1in,
)
#let pxsize = 2 // points
#let xpixels = int((pagewidth - 2)*72/pxsize) // pixels horizontally
#let ypixels = int((pageheight - 2)*72/pxsize) // pixels vertically
#let bitmapWidth = xpixels * pxsize
#let bitmapHeight = ypixels * pxsize
#let complexPlaneWidth = 3.0
#let complexPlaneLeftEdgeCoord = -0.7
#let complexPlaneHeight = 2.17
#let complexPlaneTopEdgeCoord = 0
#let maxcount = 100
#let computeRealPartFromX(x) = {
let f = x / bitmapWidth
let realPart = f * complexPlaneWidth + complexPlaneLeftEdgeCoord
return realPart
}
#let computeImaginaryPartFromY(y) = {
let f = y / bitmapHeight
let imaginaryPart = complexPlaneTopEdgeCoord - f * complexPlaneHeight
return imaginaryPart
}
#let escapeTime(cReal, cImg) = {
let zReal = 0.0
let zImg = 0.0
let count = 0
while ((zReal*zReal + zImg*zImg) < 4) and (count < maxcount) {
let nextZReal = zReal*zReal - zImg*zImg
let nextZImg = 2*zReal*zImg
zReal = nextZReal + cReal
zImg = nextZImg + cImg
count += 1
}
return count
}
#let mapColor(t) = {
if t == maxcount {
return black
}
let r = (127 + calc.sin(t / 11.0) * 127) * 1.0;
let g = (127 + calc.sin(t / 7.0) * 127) * 1.0;
let b = (127 + calc.sin(t / 5.0) * 127) * 1.0;
if r < 0 { r = 0 }
if g < 0 { g = 0 }
if b < 0 { b = 0 }
if r > 255 { r = 255 }
if g > 255 { g = 255 }
if b > 255 { b = 255 }
return rgb(int(r), int(g), int(b))
}

#let cReal = computeRealPartFromX(x)
#let cImg = computeImaginaryPartFromY(y)
#let et = escapeTime(cReal, cImg)
#let color = mapColor(et)
#place(
