Punch is a Japanese macaque at Ichikawa City Zoo who went viral carrying a stuffed orangutan around. We used him as a test case for LabGym - and the results were surprisingly clean.

Researchers in @byneuron's lab at the LSI first developed LabGym to overcome challenges in analyzing fruit fly behavior.
Now this open-source software has expanded to support research for thousands of scientists across five continents—from @jjemrick's efforts to understand pain sensation and behavior in @UMichDentistry, to @cedricsueur's studies of social roles in wild Japanese macaques.
