A kaleidoscopic journey that traces the methods and mediums of visual communication from the cave paintings of early humans to the photography of a black hole in deep space. Since the beginning of our time as humans, we have never stopped making images and inventing channels for visual communication. From the cave dweller creating paintings on a wall at the dawn of civilized times to Instagram influencers today, technology may continue to change, but our need to reach out, to move one another, to persuade, to inform and to entertain, has never been more vital. Hello, Human traverses the entire landscape of our diverse, expansive and familiar means of visual communication. From the use of the human hand as a symbol, the power and use of gestures and the genesis of the printed book, to the movement between the dimensions of reality and the digital realm, to pixilation, optics and the understanding of light, Horsham takes his readers to his world. On a journey full of unexpected twists and turns, establishing a temporal narrative in the form of an intricate map of objects, events and people united by a common purpose: to communicate.
