Red Bull Crowdcast allow people to upload live content (only text and photos for now) to both a mobile and a PC sites, in real-time. The user get a specific email address by scanning a QR-code, which is linked to an event (for example, as we did for the Red Bull Sound Clash, or, more recently, the Red Bull Box Cart Race).
Uploaded content is accessible almost immediatly, and can also been broadcasted during the event itself via a flash vissualisation module. We built also a very simple, ajax-driven live moderation tool.
I was responsible for the whole art direction of the project: from the logo and the overall look and feel, to more technical aspects like CSS and HTML integration. The project was built using the Symfony framework.
As Mike wrote on his blog,
Email on mobile phones in Japan has been a standard feature since the beginning and often acts as the primary email address for many Japanese people. It is a natural interface to participation. The time from sending your email to appearing on the stream can be as little as 5–10 seconds, so the reward for participation is almost immediate.
