Look! Especially the bit at the bottom.
What is the logical conclusion of camera design? A tiny spherical sensor that could capture all of the visual information all around it in a single photograph. A veritable tiny black hole of a thing. It is pleasing that such a device would replicate the "floating sphere in space" physical form of stars and planets. It always seems that the universe enjoys the replication of particular forms at various scales. It's all just fractals, all the way down (and up).
