Go with the Flow (by Filippo Cuttica)

Go with the Flow is a new way to visualize email. Built of tubes and wires, the contraption filters your incoming emails into three cylinders – work, family, and friends – and colours them accordingly. That’s kind of neat on its own, but here’s where it gets interesting: you actually haven’t received any emails yet. They’re just backed up and chillin’. To receive emails, you operate valves beneath each tube, allowing water to trickle down into a physical inbox. Depending on how far you’ve opened a valve, you’ll receive a proportional amount of emails from that category.
