A bunch of otters jam on a Casio. An orangutan plays a xylophone with a banana. A sloth bear toots some harmonica. These are all a part of the National Zoo's environmental enrichment efforts, not unlike getting your cat some food balls and cat shelves. [more inside]

Artist Doug Aiken's projection installation, Song 1 on the façade of the donut-shaped Hirshhorn Museum in DC opened last night. The work is a looped video installation of many people singing "I Only Have Eyes for You." It's very atmospheric and finally brings some art that enlivens the somewhat strange shape of the museum's exterior. I heard him speak and then got to see the installation. It's beautiful. If you're in DC definitely come down to the National Mall after dusk (projection runs nightly until midnight).

For those who enjoy exploring the possibilities HDR presents, a good place to start is Stuck In Customs. Trey Ratcliff has the first HDR photo ever to hang in the Smithsonian. He offers a comprehensive, six-step HDR tutorial if you want to try it yourself. A sampling of his HDR travel photography is here, and throughout the site, and he is also experimenting with HDR video technology. [more inside]
