Well the plugin is pretty much ready so I'll include it in the next release.
Unlike my flame object, this allows for multiple colours (as opposed to having a greyscale image that maps against a drawn gradient). So this example demonstrates what happens if you draw some coloured circles and paste them into the flame.
