Here's my debugging image. It's just a fully emissive sphere tangent to

the emissive sphere to fully illuminate the shapes (100 samples/pixel):

Here's a couple more interesting images. The buddha is 100 samples/pixel and the
dragon is 256 samples/pixel. The buddha is surrounded by a fully emissive sphere
while the dragon has a large emissive plane above it, though it is not in the viewing
window:
