A revolution in gaming when it first came out, and still many other possibilities when it went out of fashion. The original function of the eye-toy was the game on the ps2, that involved players using themselves in a reflected position to play games with their hands, feet, even head.
But after this game went cold, i realised that i could use the Eye-toy as a webcam for my pc, instead of buying an actual one. I searched through the internet for the drivers and bam! i had a working webcam.
The quality of the thing isnt too bad either. Ive dropped it many times from heights above 6 foot (not on purpose!) and nothing has even scratched it.
If i had to have one criticism however, it would be that when its on as a webcam, the red light that shows its on can be very distractng, as you just want to stare at it, or thats just me. Anyways if you have an eyetoy, dont throw it out, it may come in useful sometime, it did for me
