shqq: Embedding shell commands in Haskell code
Shell scripts make it easy to pass data between external commands. But shell script as a programming language lacks features like non-trivial data structures and easy, robust concurrency. These would be useful in building quick solutions to system administration and automation problems. As others have noted,12345 Haskell is an interesting alternative for these scripting tasks.

Quasicrystals as sums of waves in the plane
This quasicrystal is full of emergent patterns, but it can be described in a simple way. Imagine that every point in the plane is shaded according to the cosine of its y coordinate. The result would look like this: 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 fe
