I've been poking around with something that will hopefully make it easier to customize blade styles: Style Editor
It still needs work, documentation and a few effects aren't implemented yet. (Like fire blade)
But, I think it's finished enough to let people play around with it and tell me where the bugs are.
Caveats: Colors, frame rates and implementations are all a little different, so some effects may look different on the saber than in the editor.
I built and tested it in Chrome, no idea if it works well with other browsers or not.
Please leave bugreports / comments / suggestions in this thread.
