This Rnd is for verify if a idea can work, which suddenly appeared in my mind after watch Khye's video vimeo.com/64173216#at=0
the tow important point in create a plasma is how to get a turbulence field and the sub trunks.
there hasn't any node like turbulence in TP, so I used point3 instead(XYZ value all defined by a noise control in curve editor) add this point3 node to position to jitter the lines. and born the sub trunks from the particles of main trunk.
as you see, the tool still have some bug and some feature which I want but not added yet, hope has enough time some to complete it.
here is rendering result vimeo.com/64708938
