Interactive LED Coffee Table

Found this video about an interactive LED table. What sprang to mind was how useful is it? It reacts to motion and looks cool. I suppose aesthetics play a very important role. Even though it is not of much use, people (including me) still think it is a cool thing to have. Most people don't own things like that. Maybe that is why its still 'cool'.

In the future as technology progresses would things like this still be interesting and 'cool'?
