Quasicrystals as sums of waves in the plane

Quasikristalle kurz erklärt.


Imagine that every point in the plane is shaded according to the cosine of its y coordinate. The result would look like this:

Now we can rotate this image to get other waves, like these:

Each frame of the animation is a summation of such waves at evenly-spaced rotations. The animation occurs as each wave moves forward.
I recommend viewing it up close, and then from a few feet back. There are different patterns at each spatial scale.
