These are some photos and videos I've taken over the past few years, a combinations of things seen in the lab and things seen in nature. The sources of many of the patterns are still open questions for me!
Salt migrating through snow
Salt stains on a Chicago sidewalk
Mammatus clouds in Boulder, CO
Folds in banded gneiss
Expired SU-8 after spincoating (oops)
Lichtenberg figures (?) in ice slush
Lichen exhibiting front-like growth
Slush patterns on Lake Michigan
