Nice. Call me crazy, but I think the squares should get smaller towards the top, just as in a real arch. I would hate for the logo for a hot new language to be architecturally unsound. Also, I like the proportions of the St Louis Gateway arch: 1:1 base to height. Neat since it looks taller than it is wide. (530 ft both) Oh, and I like 9 thing daniel mentioned.
I have tried that but five is the minimal amount of pixels to form an arch and minimalism is one goal of pg, isn't it?
The proportions are derived from the underlying pixel grid. I wanted the logo to be scalable without blurring by just multiplying the pixel number.
