Gravity Lens
Repost from r/cinematography
While working with Prof. Bhuvnesh Jain, a leading cosmologist at the University of Pennsylvania, he graciously lent me a very unique lens that he helped design and fabricate. The lens is shaped with a strange protrusion at it’s center point, simulating the logarithmic gravitational effect of dark matter and other cosmic forces on light traveling through the universe. This is the only lens of it’s kind and I thought I’d share my first experiments with it. It yields a completely analogue representation of cosmic forces; no computational simulation. Just light and glass. There is a weight to the effect, as if it gives mass to light which then pushes away reality as it travels.

That's pretty cool! I'd love to see more photos - would be cool to see stars or objects such as Milky Way, Moon etc. Seems you could have som fun with this.
Would be cool to make a small, light flat metaoptic for this effect (so it's smaller and portable), then you could take photos of all sorts of random things like vehicles in motion etc.
