This script will tell you the names and distances to all people within 96m every time you say 'detect' on channel 1. Unfortunately, there's a 255 character limit on the amount of floating text, so beyond about four or five people stuff starts disappearing off the end of the string.

How about less useless information then? And fewer hyphens. >.> - Katharine Berry 19:28, 23 July 2007 (BST)
