Heart Spark Jewellery Lights Up To The Beat Of Your Heart

This heart-shaped pendant, made to look like computer parts, has LEDs that flash in coordination with your heartbeat. In the future, the pendant will even be able to log data regarding your heartbeat.

It’s a sorta geektastic gift a semi-chic, ubergeek might enjoy. The Heart Spark is available for a trial cost of $US69. [Sensebridge via MAKE]
