Hacking in front of a kid

I've been hacking a simple breakout/arcanoid game clone last time. It uses pygame for graphics/audio/input/windows/etc. so that I can concentrate on the game logic.

My goal is to implement something cool for my 6-year old son. But also I try to show my son what daddy can do with his text editor and terminal. The game logic itself is the next to trivial for such a simple game, so I trick myself for developing new features in front him.

I must say that that is amazing experience. We do it in 10-20 minutes sessions. During that time I'm implementing some game feature, and afterwards he plays a bit. While I'm hacking he is sitting next to me and staring at python code. And for sure if I don't produce something exciting in 5 minutes or so, he get bored. So I'm coding in real time like hell. (And using dynamic language with extremely short "hack-try-fail-fix-try-works" cycle suits really well.)

No tests, no design (except some half-minute thinking in advance), just pure hacking.

At this point of time I just want to show the kid what you can do with programming. I think you need to excite somebody with before teaching them  industrial methods. Like, you buy your children Lego, and you show them what they can build with it, and then you want them to play with it. And only later on you teach them that they should design their buildings first and that they should pass some regulatory mandated tests and follow the industrial good practices. And hacking simple python games using nice game engine is just like that -- constructing Lego buildings.

I think I'm halfway done with exciting my son with programming, because after third of fourth session he asked me what it takes to be a programmer :)

P.S. Disclaimer: I make up the code a bit while he is sleeping though, so when we start next day it doesn't look like complete mess. One day I will share it on github.
