Hi, everyone 
Here goes my first extension
I've created it for my own needs and I guess not many people will be able to use it since you need a specific game controller for it. Anyway:
The Buzz Object gives you a full control of Sony Playstation set of Buzzer controllers. If you've never heard of them, that's how they look like:
Please login to see this picture.
Each Buzzer has 5 buttons: the big red one (with LED inside), called Buzz and 4 colorful buttons. The Buzzers are mostly used in quiz games where the buttons from blue to yellow work like answers "A, B, C, D" and the Buzz button is used for many various things (like pressing it first when you know the correct answer, etc).
Each set has 4 Buzzers (wired or wireless) and can be simply plugged into a USB port.
The reason for creating the Buzz object was to control the LEDs in each Buzzer and that's probably the most advanced part of this extension xD It can also simply read the button states.
As for now, there are 3 different versions of the Buzzer controllers for Sony Playstation: wired, wireless v1 and wireless v2. I've checked it with the wired ones and the wireless v2. I don't own the set of wireless v1, so I can't check if it works with them. I'd be grateful if anyone here owned that set and would feel like checking it for me 
It should be able to control up to 64 sets of Buzzers simultanously (so it's 256 Buzzers). However I don't own more than one set and also couldn't test it yet. I'm probably gonna check it soon with my friend's set.
Any info about the usage of the Buzz Object can be found in the included help file.

I'm looking forward to hear your opinions and any errors found
