Rulof Maker is always good to watch. Here, instead of repairing some plastic spectacle frames, he makes some out of wood. What is quite amazing is the good results he gets without measuring, and using a thick felt pen to draw outlines with. What is even more amazing is how he doesn't lose a finger while doing it! If you want to buy some nice wooden sunglasses (which I presume he didn't make, follow the link: https://goo.gl/BNWcfQ which probably contains his Amazon partner ID)
HackerMaker is the culture and philosophy of creating, repairing and inventing out of whatever is available. Raw materials are no longer the raw materials with which we work. Our prime materials have been extracted, cooked, processed, moulded and shaped cheaply and in large qualities to fit some purpose other than ours.
