Everything around us in our 'built' world from the the smallest trinkets to the largest buildings and everything in between is the product of human thought.
To try and image the human thought involved in creating the space you are in right now is just mind boggling. Pick out a single object like a child's toy. Mentally unwrap the plastic shell imagining all involved in its creation. Visualize the circuit board with all its component imagining then all one by one and how they came to be. Imagine the bare circuit board with all its tracks and layers and pads and for just a moment imagine you are there in the beginning, starting with an empty workspace and defining every track, every connection, every minute detail.
Our world is complex beyond imagining in diversity, technology and creativity and I could not imagine it any other way!
