title: Sketch.js on iPad
body: <p>Anyone knows how to make <a href="http://intridea.github.com/sketch.js/" rel="nofollow">sketch.js</a> work properly on the iPad? It almost works perfectly, but the problem is that once you draw a line and do mouseUp, and you want to draw some more, it does that but it erases everything around the new line you are drawing.</p>
