And I've also had the idea of creating tutorial screencasts about modern C++11 game development for beginners. What do you think? Is someone interested?
In general, it takes a lot of time if you prepare code for educational purposes, don't underestimate that. I don't know if it's a good idea to just show the code of your game, because it might be very specific and advanced (not a typical game) and thus hard to understand. If you lay it out in a strictly incremental manner, where you add feature by feature, you will have to redo a lot, because that's most probably not how you develop otherwise. It depends of course also on how detailed you want to make it -- a complete game is definitely a lot of work, but maybe it would even be more interesting to pick out a few special techniques, e.g. the way how lambda expressions can be used to make code simpler and more powerful? This approach would also have the advantage that people don't get bored by the lengthy parts of game development (boilerplate coding without interesting functionality). And you could keep the videos rather short and directly focus on the interesting parts...
If you do it, then please make sure you really use modern C++. Not such a mix of global variables, arrays, manual memory management and macros like CodingMadeEasy... Then it would be a good contrast to these videos based on ancient code style
