Some say it is a UFO, others that it is a ring, albeit a mighty big one. But what it really is, is Apple’s latest headquater design for their Cupertino Campus. It is certainly striking, take a look here:

They plan to build on their 40 ha site with lots of landscaping as well and you might notice that there is no sign of carparking for the 12000 employees expected to work here. That is because multistoried carparking is provided underground, maybe Apple is taking their aestethical computer designs to the environment as well.

From the start in the 1970s when 2 chaps began building computers to 12000 now working in what this year became the World’s most valuable company is quite a story.
