Makoo is the first web-app that allows you to materialize your emotions through the creation of a unique and special jewel, by simply using your voice and 3D printing. You just need to record a short vocal message containing the words you want to send or preserve. A software analyzes the features that make your voice unique and creates a 3D model that corresponds to your message. You can then adjust the geometry to your taste with a few simple sliders, choose the material (bronze, silver, brass and gold plated brass) and the size of the jewel (you can find out your measures by using this simple tool ( link ) ). When you are satisfied with your creation, you can buy it online for yourself or give it as a gift to a second person. In both case we will produce your object by using metal 3D printing, thanks to Shapeways, our printing partner. When the jewel reachs its final destination it is followed by a surprise: a special code that will allow you to retrieve the generative vocal message and the emotions contained in it.
