rainbow-mode is a minor mode for Emacs. It displays strings representing colors with the color they represent as background.

VI takes this same paradigm of pipes and filters and simply wraps it in a editor user interface in which the pipe is applied to editing buffer both as a source and as a destination. A VI pipe is thus can alter the buffer using standard Unix filters that instantly become a part of editor toolbox. This is an extremely elegant idea. The ability to pass nearly arbitrary chunks of text through any UNIX filter adds incredible flexibility  at no "additional cost"
