If you go to Raffles City at City Hall and take your eyes off from the window displays, you may notice a water fountain that looks something like this:Some sites refer it as inkjet or smart waterfall, cos it looks like an inkjet printer printing out, just that gravity takes care of the paper feeding and now it's water instead of ink. The computer programme controls the valves and nozzles to open and close at the precise moments to create words and patterns alike.I saw some zodiac signs and some stick figures at the Raffles City's version. Maybe you should go take a look and share with me what you see.
