Microsoft has announced that it is to make some significant changes to the Windows 8 user interface, including dropping the Aero Glass effect that was first introduced in Windows Vista.
There is a massive, wraparound glass staircase, and dropping down from the 24-foot-tall ceiling is a 12-foot-long "found art" light sculpture made by a local artist with steel rods and old trumpets, toy train tracks and parts of old pistons.
In the same way the company crushed panes of competitors glass with a press last year, it's now dropping a 130 gram ball from a height to see what damage and havoc it can wreak.
