It appears that designers Yoon-Hui Kim and Eun-Kyung Kim have designed a blind that actually gives light. These individual tiles have a grid of white LEDs inside that can be clicked on in a variety of all sorts of shapes and sizes. Not only do these things make some interestingly shaped lights, but they are energy efficient as well. On one side are the LEDs, and the other side are solar cells that can charge them. So, during the day, when the sun shines on the blinds, you will have enough power to shine the LEDs at night.
Unfortunately, this is the part where I explain that these blinds are just a concept, and they won’t be available until some indeterminate point in the future. Too bad. I could really use something like this now.
