There's a new xtra in D8, which currently allows Director to save and compress any files as a .zip file. So if you need to zip stuff let Director do it. This director movie shows how to use this feature, with full open source code. Includes a convection map, for better looking flame, and can be used to add logo's, text into the flames. Clicking within the window,should start little sparks of flame.
Seed can be constant, or varible.
