Mmmm … I really like the Horton Timer-Picker, but it is not free. Is it worth $45? I am still undecided. It was perfect for in class discussions. It randomly picks a person to talk, and there is a countdown timer to keep track of how long they get to talk. This is perfect for a class where the discussion tends to be unbalanced. I can create my own using multiple tools – an random name picker and an online timer. But in theory, I like the Horton Timer-Picker.
