When I see something cool, everyone around me needs to know about it. I stumboled upon this Interactive Water Board a few weeks ago. This concept was created by Mark Burton in the Uk. He wanted to highlight the importance of water in our lives. He created this very cool interactive Water Board that will just blow your mind when you take a look at the youtube video posted below. 

You can draw obstacles on the wall, to change how the water flows. Or you can simply stand in front of it and use your entire body as an obstacle. One more cool feature is that the water reacts to the situations formed by it’s users. Land will react to nearby water sources and grow plants. Pools of water will create life and stale water will get dirty and unpleasant including the present of flies.

Here is the Video - I strongly advise watching it
