This is really nice, however I wish someone makes an in-game version of this, so you don't even have to get a development environment running - just install the mod (which kids are already familiar with), jump in game and develop there.

I was thinking about this as well, maybe something like ComputerCraft which uses Lua but build on top of it, try and make it more visual though.
