D3 Examples - Dynamic Air Force Logo

Dynamic Air Force Logo
I hand-drew the USAF logo and added dynamic drawing to it. There was a website that converted a jpeg image into SVG, then I extracted the coordinates of each point, then followed the lines to draw the outline. Needless to say, I had too much time at home at one point. Example from mbostock/bc4e32ec71636b498c46.
