The N-Light Membrane
is a cube of mirrors with fluorescent lights as edges. 3 mirrors are one-way, so you can see inside. All you can see is reflections of the inside of the cube, extending to infinity!
The other 3 mirrors are flexible, and the cube is connected to an air tank. By inflating or deflating the air tank, you can make the cube convex or concave. The reflections bend in weird ways. The effect is hypnotic.
This cube was created by an art collective called Numen/For Use
, and it was displayed in St. Petersburg. It's fun to watch videos of it shot from different angles:http://www.numen.eu/installations/n-light/membrane/
What if you did a tetrahedron or octahedron? There's no need to imagine; you can see them here:http://www.numen.eu/installations/n-light/objects/
Numen/For Use is really three Croatian and Austrian guys, Sven Jonke, Christoph Katzler and Nikola Radeljković. Puzzle 1:
can you make a mirrored box with warped sides so the reflections make it look like you're in hyperbolic space? You may have seen the 'hyperbolic honeycombs' in my #geometry
series - that's the sort of thing I mean.Puzzle 2:
more generally, what cool effects could you get from a mirrored box?
If we're in an ellipsoidal mirrored box and we each put one of our eyes at one of the foci of the box, all you should see is the pupil of my eye, and vice versa. #geometry
