New Sunglass Company out of Barcelona, Spain came up with the brilliant idea to not only let you make your own sunglasses, you can also help the environment because they come from recycled plastic. Get bored with that sunglass, you can take them back for recycling or to make another.
FOS Works is a design studio and offers workshops in which you can make your new sunglasses. Might be worth a trip to Barcelona! If not, you can always order online
