While waiting for the traffic light near the intersection of Jefferson and El Camino Real on May 20 2025, I saw this artist in a hoodie and facial mask sitting against the wall outside a Whole Foods store, with several paintings and a sign that read “painting for sale”. I did a quick sketch on my mobile phone upon arrival at the Caltrain station, but could not figure out how to proceed it until today when I used it as a composition reference for Adobe Firefly text-to-image generation.

According to Thiebaud, art cannot be replaced. So an art work, once created, remains unique. In contrast, a scientific model or theory can be invalidated and supplanted by newer ones.

Immersive multi-screen installation

The unique sense of immersion that I experienced with the multi-screen video installations of de Young’s Isaac Julien: I Dream a World exhibition could be attributed to several factors:

  • The multiple video channels provide the opportunity and imperative for the viewers to choose which one to watch, analogous to viewpoint switch in the real world.
  • The spatial arrangement of the screens provides 3D cues even if not conforming to the depicted scene geometry.
  • The spatial sound channels also help to modulate the visual experience, by guiding the viewers’ attention to different parts of the installation.
