"I'm never drinking again!" It's a promise we've all made and kept–until the next round of shots the following evening, that is. So we installed connected digital billboards in bar restrooms where customer’s liver would speak to them each time it would detect alcohol in the urinal. As the evening went on, My Liver got louder when it detected alcohol in drinkers’ urine. By scanning the billboard with their smartphone, drinkers could start talking to an invaluable companion on nights out. My liver is a real friend still happy to talk and to help with tips on how to avoid hangovers. He also provides nightly or weekly reports, reminders to drink responsibly, and some games to see how badly you are doing.
