I love the illustrations done by Chris Gash, who does the artwork for my Observatory column every week in The New York Times.
Here are two fun examples of his work, illustrating how young female chimps play with sticks as dolls, while males are less likely to, and another on new fingerprint technology.
The topics are often tricky and complicated, but he always finds a way to make the point, and weave in some humor into the drawings. His blog was fun to look through because it gives me some interesting insight into how he comes up with the illustrations!
