Gravitional lensing is one of my favorite phenomenon in physics. I did once a web version of it. Here is the link if you want to play with it.

This is awesome. Any links to source or comments on what tools you used to make it?

It's plain javascript. I used canvas and reflected the coordinates of pixels according to position of cursor. Also smoothed the effect using a heuristic smootherstep function.

Just beautiful!

At present, the title here on HN is "Gravitational lensing by spinning black holes in astrophysics" -- to which my immediate reaction, and I suspect not only mine, is: what, as opposed to in cookery?

The original article title gives the answer: "... and in the movie Interstellar". Since the article really is about the rendering techniques used in the movie as well as about the physics of rotating black holes, I suggest that the HN title be made to match that of the original article.

I saw the title and thought "is it the one from Interstellar!?!?"

Thorne said he was going to publish based on their simulations so it's awesome it's here. I agree it might be nice to have the context in the title since this is cool for both physics and science-fiction fans.

I had pasted the whole title, but ycombinator removed the part after "-" I think.

Gravitational lensing or just large magnetic fields bending light? http://www.gizmag.com/synthetic-magnetism-stanford-photonic-...
