"Through a Glass" - Interactive Online Art

"Through a Glass is a prototype for a series of images I am planning to make over the coming year. They will illustrate an interactive story I am writing.
Move your mouse over the glass view to change the time from night to dawn to day. There are also 3 set of nature songs to go with the times of day, night sounds, dawn chorus and a lazy summer day."

Nice bit of online software. Simple / elegant display.

Shows what you can do with HTML, javascript, and talent.
