Pyronova project homepage
I lied. I cannot wait until my midterm ends to finish Pyronova :p
Now it's in 1.0 Beta, and supports XML serialization.
Also, it's currently half-documented. I'll complete the documentation ASAP.
I've created this example combining Pyronova and Stardust. I think the outcome looks pretty nice :)
The logics behind this effect is rather simple: the butterflies are created using Stardust (well, that's another story); the HueNode shifts the hue of the butterflies, and the BlurNode blurs the butterflies to create the glowy effect.
