At work tomorrow, I need to give my colleagues a mini lesson on the Pi, I work in IT, but most of them have never really used Linux before. So I would like to make it seem interesting, aside from just basic navigation etc. is there anything fairly simple, but impressive I could so to show it off?
There will also be a few non IT staff in the meeting, so it doesn't have to been too technical. I can't do too much with the device, as it will be running as a mini server parsing JSON and controlling a light in the near future, and I only have about 15-20 minutes.
What do I show them?
