Things that change as you look

In the old courtyard houses of Al Fahidi in Dubai, sunlight comes through carved openings and throws a pattern across the floor that moves through the day. In the morning it is sharp and pale. By late afternoon it has stretched across the room and turned gold. The same wall looks like a different wall depending on when you stand in front of it.

That quality, something that seems to have depth and keeps shifting the longer you stay with it, is rare now. Most of what we see arrives through a flat screen, at one brightness, at one size, in the same frame as everything else. A product photo, a shop page, a feed of ads that resemble each other. It is very easy to glance, file it, and never think of it again.

Flat things are forgotten because there is nothing more to find. All of it was visible in the first second.

The work worth doing goes the other way. A shop page that reads differently once you notice the line about where the fabric came from. A box that reveals something only when it is opened. A story that means one thing before you buy and something else after.

None of this is decoration. It is depth, and depth is what keeps a thing in someone's mind after the screen goes dark.

Making something that shifts as people look at it is harder than making something that looks fine once. It is also the only kind anyone returns to.
