A little shell script that lets you generate sparklines at the command line:
spark 0 30 55 80 33 150 ▁▂▃▅▂▇You can also pipe stuff to spark—see this wiki page for some clever examples.
This is pretty cute. I like the idea of putting inside your prompt, think there’s some interesting information you pull to put there.
Maybe a graph of how many times you had to run `sed` to actually get your prompt to render?
