“The Paddle of Memory” is a public art exhibition project collaboratively created by 4aC and UCCA Lab. In the visual design, we emphasized a texture of “temporal sedimentation” — layers of color overlapping, paths intersecting, and light and shadow permeating one another, together forming an impression that feels both in motion and constantly looking back. The visual expression echoes personal memories while also reflecting the traces left by cities and industries through the shifts of time.
