By now you've probably had a chance to either play with the Windows 7 beta, or have at least read up on Microsoft's upcoming operating system and have had your share of screenshots. But what you might not know is that the Windows 7 interface was close to being decidedly different than what it is.
Steven Sinofsky, senior VP for the Windows and Windows Live Engineering Group, said that kept a gallery of designs for the Office Assistant on his office wall to help inspire the Windows 7 team. His gallery contained over 400 sketches of the desktop UI, including a taskbar with thumbnails of open windows instead of icons.
Other interface considerations include a Bat Signal, so that when you hovered your mouse over an icon, a window pop-up would appear highlighted by beams of light. This would later evolve into Aero Peek in Windows 7. Aero Shake, on the other hand, came from an experiment called Aladdin. So long as a user kept 'rubbing' a window in the background, it would stay on top.
