Using reactive paint, presumably reacting to light in this case, designer Shi Yuan has created a unique wall calendar that slowly fades away as the day progresses. It’s not only a quick visual reminder how much of the day is gone, but it also ensures you don’t use the wrong date the next day if you forget to flip it, because theoretically it will be completely blank. I also think the concept would work great for all the post-it notes stuck to my monitor. The next day when I wake up my to-do lists will have completely vanished!
