Plant a seed in one department and let it grow (Score 1)

Some of the subversive folks may like this idea. A friend and I started it several years back when we worked in a graphics lab as interns.

We ran GIMP on our laptops, we started doing some work in it. One day we installed GIMP on a SGI o2 to show a professor. That professor loved and and showed another. They realized that for the price of Photoshop they got something free, easy and better (IMHO).

Shortly there after we were showing other students how to use it. I'm not sure what became of it's usage there but somethings you have to start at the grass roots.
