Ask HN: “Let's code” – video for developers?

Hi guys,

I'm a huge fan of "Let's play" videos, where someone is playing a game and gives comments on it. I wanted to have something similar for developers. Rules are:

1. It should be short 20 - 30 minutes;

2. Code should have large font, so it is easy to read

3. Ideally it should not be a tutorial, just your regular flow, where viewers can pick up your practices and share their own advices in comments.

4. It should be free.

Does something like this exist? I couldn't find, so I made couple episodes of k-means algorithm in JavaScript.

Here is the last one: https://www.youtube.com/watch?v=4UEP2Mv8MJ0

Please let me know what you think (regarding idea or the video).

Thank you!
