Wim, thanks—as soon as I get a chance I'll see if this works for me. A potential problem is that I'll have polygons (not just triangles but squares, pentagons, etc) rotating, which means that any given shape in the larger figure will be interacting with multiple other shapes in changing ways.

An arbitrary amount of circles seemingly overlapping:

import random

number_of_circles = 10
radius = 100
wobble = 400
canvas_size = 1000

circles = []
drawn_circles = []
center = canvas_size / 2

# Create circles
for i in range(number_of_circles):
    x  = center - (wobble * 0.5) + random.random() * wobble
    y  = center - (wobble * 0.5) + random.random() * wobble
    circle = BezierPath()
    circle.oval(x - radius, y - radius, radius * 2, radius * 2)
    circles.append(circle)

# Check if circles overlap
for circle in circles:
    for i in range(len(drawn_circles)):
        intersecting_shape = circle.intersection(circles[i])
        if len(intersecting_shape.points) > 0:
            circle = circle.difference(circles[i])
    drawn_circles.append(circle)

# Draw circles, or what’s left of them
newPage(canvas_size, canvas_size)
fill(None)
stroke(0)
for circle in drawn_circles:
    drawPath(circle)
