It works, but not that well. It has a "Shareware" license, which means that you download for free, use it for 7 days, then you cant use it anymore and you have to pay. I decided not to pay, I dont need it anymore. So I drag the app to my trashcan and empty it. Simple as that right? NOPE. Now every time I open up Apple Photo Booth, I am asked, IF I WOULD LIKE TO PURCHASE IGLASSES! NO! I DO NOT WANT TO PURCHASE IGLASSES!!! Seriously, Im a computer engineering student and i still have yet to figure out how to get the damn thing off my macbook. Do yourself a favor, and find something else to use as a webcam controller.
