Although Apple's Campus 2 isn't scheduled to be complete until 2016, that doesn't mean that we can't get periodic sneak peeks of the massive project. Luckily, thanks to a curious drone owner, we get an updated look at Apple's evolving Cupertino HQ. When complete, Apple's new campus will house roughly 13,000 Apple employees. The circular building will be 4 stories and cover nearly 2.8 million square feet. Lastly, the entire outer wall of the building will be covered in curved glass making this a very ambitious and expensive project.
