Got a great business idea? You have until February 15 to pitch it to top Silicon Valley venture capitalists and win six months' free office space as well as networking and mentorship contacts from leading venture firms. The pitch must be in the form of a 30-second video that you shoot and upload from your mobile phone. You can also have your friends and colleagues upload video votes and testimonials in support of your business concept.

The contest is sponsored by MyWaves, a service that delivers video to mobile phones over 3G networks. MyWaves provides as many as 10,000 video channels that consumers can subscribe to, ranging from the sublime (religious services) to the ridiculous (college-boy humor), with everything from cooking lessons to dance concerts in between. MyWaves is free to consumers.
