Winter time can be rough in the city. The sky is gray. The weather is unpredictable. So slough off those seasonal blues with some Times Square razzle dazzle from this sweet, ultra-high-density 64x64 RGB LED Matrix. These panels are typically used to make video walls. Here in New York we see them on the sides of buses and on top of taxi cabs displaying animations or video advertisements. We thought they looked really cool, so we picked up a few boxes of them from a factory. They have 4,096 bright RGB LEDs arranged in a 64x64 grid at a 2.5mm pitch.
