Following on from publishing my Codea Library, I’ve put up a tutorial on how to use my touch controller. Whilst it probably isn’t the most exciting part of my library, as most of my stuff uses it then it seemed the right thing to start with. You can read it at: http://loopspace.mathforge.org/discussion/10/touch-tutorial.
Note: Although the software underlying that is a forum, I’ve disabled comments as it’s really just a fancy way of creating a website. So any comments should either be made by email or (preferably) here.
