Agile tools: hour glasses


I have bought several of these sets of hourglasses for my current client.

I have given every team doing a standup a 15 minute hourglass.  Next to that I left set like this in different meeting rooms.

The idea, if a discussion takes too long, anyone can turn an hourglass and make it visible that she thinks the discussion takes too long.

By polular request: You can buy the hourglasses at TeamBuilding Shop if this no longer work, you can buy them at
