Ok, this could be the best or most dangerous thing to have in your home. Dr. Whippy, an art project by british artist, Demitrios Kargotis, is an ice cream machine that serves customers based on their stress levels. You talk into the machine's mic, and it measures how unhappy you are based on voice stress analysis. How large your cone of goodness depends on how stressed it thinks you are.
Dr. Whippy has been traveling from festival to festival for the past two years. It recently made a pit stop at Ars Electronica in Linz, Austria.
