Jet bands are similar to jet packs in Second Life. This is a simple device that you wear about the wrist of your avatar. It allows you to fly above the 200m limit imposed by Second Life. This two-part YouTube video shows how to create a jet band. This is a user contributed video, I did not make it, though it is based on code from Scripting Recipes for Second Life. It is very well done and I am sure it enjoy it. It was created by Mike Lively of Northern Kentucky University.
