I love to see things that are so tangled they defy all logic to untangle or even understand their pattern.
Near our house is a Byzantine church. That in itself is so beautiful when they play the church bells with something like a piano keyboard. Anyhow, there is a huge nettle, a giant, wild hedge with small birds darting in and out.
Hundreds of birds seem to live in there. It is so amazing that they can so quickly and accurately navigate this dense and obtuse tangle of hedge at such a high speed. They must be geniuses.
