SkyRocket MultiMedia recently released Digital FireworX, an entertaining application for creating fully rendered simulated fireworks, complete with 3D particle animations and digitized sounds. The software allows users to fire off fountains, gerbs, cones, firecrackers, mortors, and rockets from the convenience of their Mac. Each fireworks effect has been painstakingly rendered and polished, and the application itself represents 10 years of development and evolution. Digital FireworX is provided as US$15 shareware.
