Someone has put up on github a very interesting experiment. An experiment I hope will succeed well. They have started a tutorial on Bayesian statistics in the form of an iPython notebook (which as you may recall allows you to embed python code, plots, text and math, into a notebook format, much like Maple or Mathematica). They have put this notebook collection up on github. This is awesome, because you can play with the examples as you learn about the theory and you can put in corrections/enhancements to the text/code and share it with everyone else.
