"Pause and look around: you will see that you are surrounded by glass. It reflects and refracts light through your windows; it encircles a glowing filament above you; it's in a mirror hanging on the wall; it lies shattered in a dented corner of an iPhone-you're drinking water out of a pint glass. Taking up a most common object, rarely considered because assumed to be transparent, John Garrison draws evocative connections between historical depictions of glass and emerging visions that see it as holding a unique promise for new forms of interaction. Grounded in everyday examples, this book offers a series of surprising insights into how we increasingly find ourselves living in a world made of glass." --Publisher description.
