Spy camera sunglasses

I recently read an article on spy camera sunglasses, which look a great idea. How often have you been looking at something when something exciting happens, but you haven't had the time to rummage in your bag to find your camera?

But these glasses are hardly worthy of the word 'spy'. The glasses are bulky and the camera obvious. To reduce the size of the glasses, they should be given bluetooth, allowing the camera control and storage of images to be on a mobile phone. This would also allow easy communication of images captured. All that would need to be in the glasses would be CCD, battery and bluetooth transmitter.
