BREAK - Mac menu bar app that lets you take a break without that co-worker giving you that "does this guy even work?" look. I made this app for a designer friend of mine that worked with a ton of judgemental jerks that don't know the benefit of taking a break from your screen every now and then. Hope you like it.
