Also #tinyCodingTip: random uniform sphere surface distribution with polar coordinates!

u = rand(0, 1)
v = rand(0, 1)

❌ DON'T (pole clusters)
θ = 2·π·u
φ = v·π - π/2

✅ DO
θ = 2·π·u
φ = acos(2·v - 1) - π/2

➞x,y,z
x = r·cos(φ)·sin(θ)
y = r·sin(φ)
z = r·cos(φ)·cos(θ)

Pure CSS illustration of concept 😼
