Sometimes it's difficult to describe your dream. Yeah? It's a pity if you want to explain something and your opponent didn't understand you at all. I suggest the scientists to invent the "Dream projector". For example, your dream is to build a house. You can show the project of it on the screen of such projector! Imagine how easy and quick the process can be! Also this device will be very useful for architects, designers, painters..! Just use the power of your imagination!
