Here's an accessory that Andrew Cuomo should really consider keeping around the office so he's prepared the next time he grills another Wall Street CEO: the Truth Wristband Kit that was just released by Make magazine. How does it work? "The wearable device dynamically reflects your psycho-emotional response to the world, promoting internal states to be externalized and made into interactive forms of expression.
