Water + Subwoofer = One incredible optical illusion [video] (thenextweb.com)

Dupe of a post that's only 22 hours old: https://news.ycombinator.com/item?id=3864994

Sure wish I could flag posts.

This was submitted yesterday, but I'll repeat some of what I said before. Someone mentioned that this isn't an "optical illusion" per se, but one that only the camera sees. I find this exploration of the gap between our vision and machine vision to be really interesting. There have been a ton of separate and great essays around the New Aesthetic that touches on some of this stuff via art (vs phenomenon).

Rev Dan Catt writes more on this too: http://revdancatt.com/2012/04/07/why-the-new-aesthetic-isnt-...

And also more cool Zoetrope-like effects without strobing:

This is not an optical illusion. It is akin to movies' special effects as best. I wonder what human sight frequency is and is there a way to alter it?
