I gave a look at the screencast and it looks pretty nice, I don't have much to suggest on that side. However I went to github to give a peek at the code and I notice there's no LICENSE file (and I couldn't find any reference to the license anywhere obvious), so may I suggest picking one up? Technically you can't define your code Open Source unless you apply a proper license to it -- actually, I don't think anyone could legally use your code as of now, because even if you wanted it to be under the public domain, you should state it clearly (I could be wrong on this last statement, if so someone please correct me).
