There are some similar ones here: http://www.recordergear.com/camera-glasses/ http://www.recordergear.com/camera-glasses/. They aren't exactly the ones I meant, no longer having the manufacturer's link. You can also find a bunch here: https://www.ebay.com/sch/items/?_nkw=1080p+spy+glasses https://www.ebay.com/sch/items/?_nkw=1080p+spy+glasses, but at ebay I'd rather spend $100 instead of $12 for these types of things.
