Notes:
- It *could* be that 1 Houdini unit = 1 angstrom (which is 0.1 nm)
- I'm recommending to stay away from refractive materials in rendering. This is due to the fact of this particular group of students having limited rendering resources. If however you have those resources, go wild!

Mo had the pleasure of joining Dr. Jeroen Claus of http://www.phospho.co.uk, teaching a visualization workshop to students at university of Maastricht. The topics covered were protein and lipid membrane rendering in Houdini using KarmaXPU.

Also check out our lipid membrane tutorial here: youtu.be/kD2aRuK8IY8
