In this stock motion clip, a wave formation of black triangles moves up and down in a random pattern. As they fall, they reveal a gold-trimmed side which reflects the light. There is a single light source which glows from above. This would make an excellent choice for VJ sets, motion graphics backgrounds, and product videos. This clip is in 4K resolution.
