Digital Camera in a Mask

Heard from a friend this morning about this new camera mask (as shown above). It seems to be a really novel gadget and great fun. It doesn't cost a terrible amount of money and wondering if it's worth a try. Am still thinking about the Olympus waterproof camera but the fact it doesn't have a view finder worries me cos not so sure I can get what I want by just looking thru the screen. The above could work if I swim out into the waves and get some interesting close ups of windsurfing. Not quite sure of the distance clarity (haven't exactly looked into it in detail) .
Have a look on this website
