Sunglasses that conceal a 4 GB USB stick is not quite what we mean by 'optical storage,' but ok.
Want to look cool and hip with the latest pair of Calvin Klein sunglasses? Then you might want to have a look at these, which pack more than just UV protection for your eyes.
Built into the sunglasses is a removable part that breaks off as a 4 GB USB stick. For those who find packing a USB stick in their pocket or as part of their key chain too much to handle, this could be the perfect solution.
Then again, it'll be a little sad when 4 GB will be considered woefully small and your sunglasses are technologically obsolete.
Expect them this October for around $200.
