Most of us would think that tiles are just that - tiles, right? Apparently not, as these tiles you see here are actually "textured glass tiles that alter in color with changes in temperature." Nice to know that these are not conceptual designs but are very real, and they are being prepped for a commercial release any time now. It won't come cheap though, as they will retail for approximately $15 per standard size 4" x 4" x 3/8" tile. Having these create a wall in the bathroom would be cool, along with placing them on the floor to see "footprints" appear as people walk on them. Unfortunately, it will cost you approximately $150 per square foot, making this out of reach for most people who are rather cash-strapped right now.
