Sonic Screwdriver, Classic Bundle Version 2.0

"The sonic screwdriver is a fictional tool in the British science fiction television series Doctor Who. Its most common function is to operate virtually any lock, mechanical or electronic, unless it is Dead-lock Sealed. If a lock is Dead-lock Sealed then the Screwdriver is useless.

If not Dead-lock Sealed, they can open doors for escape, exploration, or seal them for protection. The screwdriver is useless against wood. It has also been used for repairing equipment, as an offensive weapon, and occasionally even to drive screws. Like the TARDIS, it has become one of the icons of the program, and is closely associated with The Doctor."

Well now you know what it is, but what does it do in Second Life? Simply put, it opens doors. Granted, this is Second Life and every door is scripted differently, making it impossible for any one device to open all of them. So to get around this little problem, the sonic screwdriver creates a door for you. Simply wear one of the screwdrivers, enter mouselook (press M) and aim at a wall, floor or other object. Once aimed, click the left mouse button and in a second or two, a glowing portal will appear in front of you. Exit mouselook, touch the portal, and you'll be whisked safely to the other side!

Novatech sonic screwdrivers also feature a scanning mode, which provides detailed information about any avatar or object targeted. And with the optional API kit, you can create custom effects. Make doors open, objects explode, or anything else you can imagine.

If you want to change the particle and light color, simply edit the color of the screwdriver's root prim. The light and particles will automatically match. You can also edit the portal's appearance and sound effects.

As of this writing, the sonic screwdriver set includes five unique models.
