Some particles test done for my friends @BlackLab Vfx who had to do a videoclip and asked me what was possible regarding this kind of effect in Houdini.
And i said "Everything !", although i'm far from being really productive with the soft right now... ;)
Anyway, i thought i would put it online as i think it looks kinda cool.
Done with Houdini version 15, Indie Edition.
