Kevin and Mark's rings were a huge hit with readers when we featured their wedding, and with good reason: they showcased the pattern of their own brain waves while listening to each other's heartbeats! Here's what they had to say about it:

The rings were a team effort: a neuroscientist friend measured our brain waves with a portable EEG machine while we listened to each others' heartbeats. The brainwaves were then etched onto a palladium band by our friends at Silver Bonsai Gallery.

Brains, hearts, charts... it's all the science of LURVE! You'll definitely want to see Kevin and Mark's rainbow psychedelic three-day wedding if you haven't already.
