Intro

So just for the record: I'm a complete LSL n00b. So don't expect much from this page. 'Cause I love the Open Source concept, I'd like to share some of my scripts with other SL Residents =)

Simple Countdown

This script displays a hovering countdown above the item it's placed in.

Basic Notecard-Reader
