[olug] Presentation on Free Software at Maker Faire-what to include?

[dthacker]

I'm going to give a talk at Omaha Mini Maker Faire on "Cool Things you can do 
with Free Software"   The audience is likely to be computer and tech 
hobbyists, not necessarily professionals.   What would you recommend I cover?

Software that's being considered.

The Gimp
Blender
Audacity
Stellarium
Libre Office
Krita


Any other ideas from the group?

Thanks!
