Making something out of nothing

Imagine that everything that was made by man began as a single thought. Your furniture, appliances, automobiles, and airplanes originated as a thought in the mind of its creator or inventor. Once the idea took hold, it moved into manifestation as a physical object. That process evolved from thought to possibly a blueprint then to what you see before you. Think about the buildings that surround you. The architect held an image of the specifications for that particular building. That information was communicated to the contractors who executed that image into what eventually became a home or a 120-story skyscraper. There is always an evolution into what new ideas are created that stretch our imagination beyond what currently exists. The same is true for a piece of music or art. The composer or painter takes the notes or paint and puts it to paper or canvas. The result is a symphony such as Beethoven's 9th or an artistic masterpiece such as The Last Supper. Since the mind can create an endless source of ideas, the results of these thoughts are also endless. What was the last thing that you manifested that began as a thought in your head?
