Last year we came across the Rotoflexion massaging backpack, but alas it was only a concept device. However, someone out there was enterprising enough to turn the idea into reality with the Airoā€”a backpack that can apply massage, vibration, and relaxing heat to sore shoulder and back muscles. Unfortunately, it appears that they failed to make the device into a functional backpack, which seems like a missed opportunity to me. After all, if I am going to walk around looking like a freakin' turtle, I should at least be able to store my books in the thing. [Discovery via BookofJoe via DVICE]
