Open-plan offices are becoming increasingly common. While they allow us to collaborate and share ideas, they can also distract us when it’s time to get the job done. Luxafor offers a series of products that help cut out the noise—literally and figuratively—and help you focus. Their ‘Flags’ are USB powered LED flags that shine either red or green indicating you are open for a chat, or would rather be left alone. The company also makes other nifty open-plan office tools from room availability signs to noise cancelling headphones.
