This is a stack of 4 separate matrix LED panels. They each have a secret button that can be pressed to select from about 20 different pre-programmed animated patterns. These range from sawtooth or random shaped travelling waveforms, geometric patterns, random jittering dots, pulsating bargraphs, counters or random numbers. The second one down only is mounted in a painted black case. The others all have naked back & sides & are intended for panel or rack mounting in our server or desktop cabinets.
