I have wasted more than an hour trying to locate it on the Flickr site, but none of the expected search terms seem to have located it.  If you know, or are, the author, let me know.  I’d like to give you proper credit and send the link to the proper page.

The Virtual Sky is made up of luminous LED-equipped ceiling tiles that project a low-resoltuion moving image suggestive of clouds moving across the “sky” above office workers.  These lighting panels simulate dynamic changes in lighting in a way that is not directly obvious to the naked eye so it doesn’t distract people from their work, but fluctuates enough to promote concentration and heightened alertness.

Unfortunately, with nearly 300 LEDs per ceiling tile the system is still rather expensive, but they expect production prices to come down significantly — perhaps because they are now using the virtual sky to improve effecency at the factory that makes it?

I don’t know about you, but I think these would be cool for use in homes, too!
