The Twilight air purifier doesn’t feel like any device we see in the market now. This concept device cools and circulates the air in your room, offering users a cool breeze that can be adjusted to your desired temperature and mixed with a fragrance of your choice. The cool part is that it sports an OLED sheet over the panel’s surface, allowing you to display images or play videos that you’ve downloaded directly on it. To be honest, with the recent trend of making everything tweet, we’re quite surprised that this concept doesn’t include Twitter built-in.
