Personal project. I've always liked visuals representing flowing blood cells, so it's almost naturally that I created some visuals of my own. The final trigger came when following Giorgio Luciano's course at CGMA (BioMedical Imaging in 3D), so big thanks to him.
All scenes were built in Houdini and rendered with Arnold (Htoa) GPU, which allowed me to keep pretty reasonable rendertime... Postproduction was done in Fusion.
