The Shumway Open SWF Runtime Project 99
theweatherelectric writes "Mozilla is looking for contributors interested in working on Shumway. Mozilla's Jet Villegas writes, 'Shumway is an experimental web-native (Javascript) runtime implementation of the SWF file format. It is developed as a free and open source project sponsored by Mozilla Research. The project has two main goals: 1. Advance the open web platform to securely process rich media formats that were previously only available in closed and proprietary implementations. 2. Offer a runtime processor for SWF and other rich media formats on platforms for which runtime implementations are not available.'"
