Developed as an exercise in physical computing and use of sensor, Heart Attack is an arm-mounted "light cannon' that is activated by the wearer's pulse.

The idea is inspired by a Character of a computer game he played, The Character has a weapon hocked on his arm, and Teng tried to use the heart rate sensor to make his heart beats visible, so he combined these two ideas and came up with the concept that the weapon is powered by the heart beats of whom wearing it.

Connected to a heart rate sensor strapped to the wear's chest, Heart attack's arr of LEDs blink in time with their heart beat.
