GIMP? a good graphics software!!!
Of Course!!!
Film animation was ealier or SGI, now most of them are moving over to MacOS X, Linux was just used by one or two films (I think Titanic, but again they are rumours, no hard facts).
Lord of the rings, Toy story, Chicken Run all used linux render farms.
Yes so many movies made with linux, Titanic also used linux clustering. Total 25 machines(24 frames per sec.).
Well, GIMP also has a user group Check out -- http://gug.sunsite.dk Just see the images made with it in gallery section, would be enough to know the power of GIMP.
