Open source Software is by and large awesome. If you work for a large company the barrier to adoption is sometimes overwhelming. In fact on one of our large projects, our employee schedule forecasting system was set to use the normal java open source stack, struts, hibernate, ect. There was a fear to use open source so our company ended up purchasing a framework from big blue...Our company has also adopted CVS instead of Subversion because maturity model score for subversion was too low.
Well some folks in Amsterdam took it upon themselves to make a movie using nothing but open source software. The result is something I couldn't believe. An entirely open source movie, free as in beer and free as in source code. Its slightly out there in plot but the graphics are quite simply amazing. Take that Pixar.
