# * Render a live-updating instance of the common monitoring application "top" in the background.

# * Play the "Bad Apple" video in the background.

# Usually when a command exits Tattoy shows an error notification. But you may want to render a
# command that outputs some static content, for example to print out some ASCII-based image:
# `command = ["chafa", "/path/to/wallpaper.png"]`
# Bare in mind that there's currently no config to re-run the command on terminal resize.
