A Hummingbird Beats Its Wings represents four dimensions in two.
It is scientifically accurate and informed by the data from Quantifying the Dynamic Wing Morphing of a Hovering Hummingbird (by Masateru Maeda, Toshiyuki Nakata, Ikuo Kitamura, Hiroto Tanaka, and Hao Liu).
The polar axis orients the viewer, and signals simultaneity.
Simultaneous events are aligned horizontally.
Color indicates the position of the movement on the wing,
while shade indicates position in time.
An imagined 3D model of the movement helps put the two views of the movement together.
