Thanks Troy,
Great moment in time! But was he roaring or just having a big yawn?
As some readers will be aware, the Mandrill has a strong connection to
the history of computer graphics as this front-on image of a Mandrill's face
was used extensively by computer graphics academics in the 70's, 80's and 90's -

The image may have originally come from the University of Southern California
Signal and Imaging Processing Institute circa 1977 and was commonly used
in various benchmarking tests. After the famous University of Utah "Teapot"
it was probably the most famous piece of iconography in computer graphics.
