Do you by any chance have some links where I can read more about Linux as a front-end system in the film/graphics industry? This is field of work in which I would never have guessed Linux to be strong.
There are exceptions - some apps (ZBrush) don't run on Linux, so there are Windows machines around, but in general >= 95% of machines the artists and developers use are Linux at the big places.
And most of those apps use OpenColorIO as a framework for handling colourspaces.
The lineage is from SGI, where many of these applications were born, but as the company faltered and consumer graphics hardware took off thanks to gaming, Linux became the natural home.
(I've worked at a few of the larger VFX studios mentioned throughout the thread)
