Was looking at a fishing website that I use and found this video

Sunglasses with a video camera built in, records sound as well.

I dont think they would be any good on a bike YET, unless you wipe the soundtrack and add music

imagine how good this would be once the mega pixels get up, currently only 3mp

I met the bloke behind these things at a car show recently. He reckons the cops and big security companies are interested, as are TV people for horse racing ( jockeys eye view) and tons of other stuff he was talking about. The bloke had huge ideas its whether they come off or not

I've seen video sunglasses for years on the Chinese sites. Unless they have changed they usually have bulky arms so they are easy to spot, ranging in price from $30 - 70 - the latter usually having IR for night. They often (not always though) have stupid colored lenses, like light blue.

They look like the Chinese ones....
