The vbs code below continuously sends a command to toggle the caps, num, and scroll lock keys, causing the indicator led lights to turn on and off, like disco lights.
It's so cool, it even became a winamp plugin (yes, I'm that old). Ok, maybe the plugin didn't work exactly the same, but close enough.
vbs code - "disco lights"
Set wshShell =wscript.CreateObject("WScript.Shell")
do
wscript.sleep 100
wshshell.sendkeys "{CAPSLOCK}"
wshshell.sendkeys "{NUMLOCK}"
wshshell.sendkeys "{SCROLLLOCK}"
loop
