This NASA visualization shows the distortion you would see if you watched one black hole and its accretion disk pass in front of another.

NASA has released a stunning new video and images visualizing the distortion you would see if you observed two black holes, and their visible accretion disks, orbiting each other.
The visualization depicts a fictional black hole that is 200 million times the mass of Earth's sun and a second black hole that is 100 million times the sun's mass. The accretion disks in the visualization are colored red and blue to more easily show the distortions.
"Viewed from near the orbital plane, each accretion disk takes on a characteristic double-humped look," NASA wrote on its website. "But as one passes in front of the other, the gravity of the foreground black hole transforms its partner into a rapidly changing sequence of arcs. These distortions play out as light from both disks navigates the tangled fabric of space and time near the black holes."
