There was a time in my team where we were taking just too much time and derailing in our daily standups, and the manager wanted to have a way to control how much time each one of us took during our standup and leave any further discussion for the 16nth minute. I created a [DSU timer][0] for the team which we used for quite some time and it served it's purpose. We later switched to another approach for our standups. It's currently [hosted][1] on github pages.
