  I do not know much about that. Here is a simpler thing you can try:

  yes sir.....

  i want to know the mechanism and is it controlled by aurdino or embedded or c programing?

  There is some physics involved. Once a water drop leaves the nozzle it is in free fall. To retain the shape one has to compensate for varying velocity in the vertical direction. All drops in a horizontal line will stay that way. The pattern will tend to stretch in the vertical direction if the fall is too long. All associated water dispensing mechanisms like nozzle design, solenoid valves and such should be matched to the control signal pattern and speed.

  I guess similar fountain is in Osaka station which displays time and its better to start building with such fountain as mall fountain is like advanced version of it. You may required a algorithm which convert the pixel pattern (of image or alphabet )into number of signal can provided to each water nozzle. It can be similar to the rolling message displayed on LED screen but in this case vertical one.
  Along with controlled signal pattern to water nozzle, if synchronous signal pattern supplied to light control panel , will gives a enhanced effect to fountain.

  Sir,
  I Actually need to know how this collapsing water fountain works,and what all requirements are needed to prepare this.
  does this need any algorithm??

  You are saying pixel. Does that mean it will done only through matlab??

  Each drop of water is one pixel. You should have a horizontal row of nozzles separated by the distance needed for the resolution. ensuring that there is some gap between the drops to avoid fusion of drops. You then work out the sequence of which nozzle drops when to create the pattern you want. Use a suitable interface to operate the solenoid valves or other valves for the operation.

  Actually this is not a simple project, But really interesting one.
  
  Here several valves are opened and closed based on the timed pulses fed to the valves. This can be done using Embedded C, and also using Mat lab.
  
  But don't complicate it too much use a very simple logic to vary the speed of valves opening and closing and you have this thing done.
