If you have a PS2/PS3 Eyetoy, but don't want to go and spend $30+ dollars on a new webcam, then this is for you.
If you have a PS3 Eyetoy I believe it PNP compliant and thus compatible with most operating systems. Simply plug it in and you should be set!
If you have a PS2 Eyetoy, then you will need to install a custom driver for it to function properly. Go to the Youtube video posted below to see how to do it and where to download the drivers. I did not make this video, but I used it to configure my own Eyetoy and I can verify that it works.
