Whilst visiting Chengdu in China we came across this amazing LED staircase.

The entire staircase appears to be in motion with scrolling text and images as you climb it in the local shopping centre. Very cool.

Chengdu is also host to the new New Century Global Center which is big enough to hold 20 x Sydney opera houses. It even includes a huge 150-metre-long screen that projects artificial Sunrises and Sunsets 24 hours a day to protect residents from local smog.
