(Rewrote attach and on_rez events and removed llResetScript(). Assignment of computed perm mask to permFlags can't be done in global definitions. Pointless asking if it's attached to owner!)
(Cleaned up. Tightened perms checking. Removed erroneous camera references. Added sanity checks. (With assistance from Innula Zenovka))

Uses tons of useful functions and a great example for those starting out. I've had tons of fun with this and all its variants i've made in my time here in Second Life. Obviously only can be used were you can rez and run scripts. Corrected and improved.
