Last weekend my DIY Air Hockey Table (PDF) instructable reached one hundred thousand views! It was a huge succes when it was published in 2009. It got mentioned on several blogs like Make:, Lifehacker and Slashgear and was even translated into Russian on habrahabr.ru and Spanish on taringa.net!
So built your own air hockey table for cheap and spread the word!
I've been making several optical corrections, such as better flowing lines by adjusting the curvature in characters like P and h, thinner horizontal strokes in all characters, smoother elipses and a whole lot more!
