I couldn’t allow myself to visit FabCafe to only talk and not make anything. So I returned and had one of the best espressos of Tokyo while I worked out a parametric Pixelglasses definition in Grasshopper.
You define the outline of your glasses with a vector line that you load into grasshopper. The size of the pixels depends on your material thickness. You can set the length and width of the glasses as well as the opacity of the hollow pixels. They work by the same principle as the shutter shades made famous by Kanye West.
The download link features some of the designs I made in collaboration with friends and visitors of FabCafe as well as the parametric system. The Grasshopper definition is slightly buggy and still work in progress. Contact me if you get stuck.
