I am having a positive reaction to this site
for the following reasons....
The bookmark metaphor
The color coded medium identifiers (colored dots, key in the top left)
Getting a nice preview of the work
Navigating with arrow keys
It mimics the experience of walking through a gallery.
It utilizes the wide screen (i have one so I like it)
I'm so so about the audio announcing each artist. As a an English speaker I enjoy hearing how to pronounce the names. It is a bit futuristic and creepy though.
