Teaching an egghead lesson should feel like walking the audience through a set of instructions. Do this, then that, move that, twist this, finally push that. The audience wants to see you putting the code together. Assembling your demo while they watch makes it feel much more real and achievable.
I though this lesson would suggest some tools to do the recording, with nice video and voice. Tools for cross-platform, tools for Mac only, linux only and/or windows only.
What would you suggest for Windows users ?
