Each Trilife circuit board controls a single LED and plugs into three neighbors. An array of boards produces spiral waves based on a simple rule: turn your light on if one or more of your neighbors is on —then fade out. The 10-component Trilife soldering kit is designed for large groups learning to solder. The open design enables anyone to enlarge an existing Trilife array.
