What to tell 13 year old kids about Linux and Open Source?

[Gabor Szabo]

hi,

in the school of my son they are interested in getting some 1 hour long
presentations from parents about various interesting subject.

I could talk hours and days about Linux and Open Source in general
but I wonder what do you think. What would be interesting to 13 year
old kids?

I am not sure "free speech" is interesting to them and unfortunately
they are probably used to that every software is "free beer".
Given the cheats and cracks.

So what do you think?

regards
   Gabor
