Additions:
The speed at which it gets through a set number of repetitions will vary wildly according to your computer's capability. By default it only displays one dot per 100 cycles - I'm considering changing this as to get a 12 hour run on newer, faster hardware (the server running this site) is going to take on the order of fifteen million repetitions.

Prayer Wheel is a short BASH script designed to be a sort of electronic prayer wheel. It sends the prayer to /dev/null (the unix device that silently drops all input -- this can be equated to a sort of black hole, or always-empty trash) for a specified number of repetitions.
I've used this to effectively provide continued 'power' for other work - in particular for a protection ritual which I wanted to remain energised and 'active' overnight, when I wasn't actively focussing on it.
#!/bin/bash
# Prayer Wheel prototype 1
# Usage: ./prayer_wheel <reps> <message>
# Example: ./prayer_wheel 500000 "Protect Her"
#
# Script echoes <message> to /dev/null for set number of repetitions.
