Vending machines are no longer just logo-covered boxes that trade coins for products. Over the past few months, we’ve covered everything from Hot Wheels’ tweet-powered vending machine to Coke’s slender, patriotic, and peace-seeking ones.

Now, coffee roaster Douwe Egberts has equipped one of its java-dispensing machines — which resides in a busy South African airport — with facial recognition software, enabling it to recognize when a person yawns. When a sleepy traveler approaches the machine, he or she is given a complimentary cup of joe.

The catchphrase attached to the accompanying campaign, created by Joe Public, is simply: “Bye bye, red eye.”

Forget blocking Facebook…a yawn-detecting coffee dispenser might just be the office productivity-booster the world’s been waiting for!
