Busy Status Bar is a productivity multi-tool device with an LED pixel screen. Displays a personal busy message. Built-in Pomodoro timer and Apps. Fully customizable, open-source, and hacker-friendly.
Probably the most over-engineered way to show that you're busy and keep track of when you should take a break....but I love it. It's a great way to make a "business alarm clock" to help focus while showing everyone else who isn't connected to you digitally that you're current locked in. It's like a physical DND.
