Suggest a "Stop All Animations" button be added to Animations selection frame for convenience. There are two versions of this script. The original by Kelly Linden above and a copy from Kireji Haiku below, who hasn't added anything to the script but reformatted it for better readability.

//HTML-based, single script HUD
 
//
<lsl>// HTML Based, Single Script HUD
// To use:
// This is intended to be a tech demo of what html on a hud allows.
// - create a default prim (cube)
// * Interaction with SL world (give items, play animations, scan nearby avatars)
// - wear it as a HUD on top_left (script needs tweaking for other attachment points)
// * Simple, low overhead (1 scripts, 1 prim)
// - edit the cube while wearing
// * Rich, dynamic interface (images, menus, flash)
// - add animations you want to use
// Updates and improvements are welcome at http://wiki.secondlife.com/wiki/HTML_HUD_Demo
// - add notecards and objects you want to hand out
// - add this script
// To Use:
//
// * Create a cube and wear it as a hud on the top-left. (script will need tweaking for other spots)
// License:
// * Edit the cube while wearing it and add this script to it.
//   This script itself is free to share, modify and use without restriction.
// * Add any animations you want to play to the object
//   Any linked or referenced files are not included in this license and are licensed by
// * Add any notecards or objects you want to give away to the object.
