Houdini - Text Particles Wings Test

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.
