Well, as far as I can tell, the lissajou addon above is working on my Mac (while your volcanoes addon isn't).

Cham wrote:I just re-tested your volcanoes addon. Well, after time 2454854.77083, it doesn't work at all.
But why this date ? The volcanoes should be ON at any time.

I do not have further ideas. 
Anyhow, I'm happy at least the curves works, because an orbital object emitting particles ( as you can see I can't wait for the particle engines), is what that there want for a binary sistems stars+black holes.
