A new rendering submitted by Apple is of a proposed 13,000 employee mega-campus in Cupertino, California. The rendering depicts a roof made of dark-grey material and jogging path and also few modest changes in the ancillary fitness center.

On Tuesday, the City of Cupertino has posted an upgraded "Apple Campus 2 Project" rendering. The newest version is high in quality, and a better-lit version of the basic original design. The images also seems to display a darker colour for the roof.

There are many other minor changes which include a few additions in parking for the corporate auditorium, an expansion of the corporate fitness center from the original 25,000 square feet to 45,000 square feet, drawings of a private jogging path and other changes, as reported by Apple Insider.

The project was first revealed by Apple co-founder and former CEO, the late Steve Jobs at the town hall of Cupertino in June of this year.

Jobs had said, "It's a little like a spaceship landed." Jobs described the building as circular shaped with curved glasses all around. In short, this is one of the most anticipated buildings in modern times which might redefine architecture.
