A guy called Eric Edwards, a motion graphics student at the Savannah College of Art and Design, has done a rather cool television-style advertisement promoting the use of Firefox. It’s a student project which he’s planning to enter in an Adobe design contest.
The style reminds me of the original techno-industrial Mozilla artwork (like the banners).
If you like it, he’s looking for internships and jobs at the moment. And yes, he did get permission to use the trademark. :-)
