I run Office Snapshots (first link) and hadn't seen the faux ceiling you linked to -- definitely interesting.

@kakkun My guess is that it would be limit direct sunlight, though if that were the case, a shade higher up might look better.

I do remember someone telling me that if you go into a Costco food court people often gravitate to the tables with an umbrella on them even though they are indoors. Their theory was that people do like to have something over their heads in such a big warehouse-size space.

What's the purpose of the faux ceiling? I would have hoped the large expansive space and glass ceiling would be used to help alleviate feelings of claustrophobia.
