At midnight, Johannes Girardoni’s website is red. It takes the next 24 hours to work its way through the spectrum and get back to where it started. You don’t have to watch the whole thing.

The opening view is called Spectral Time. It was designed in close collaboration with Girardoni, a multimedia and installation artist based in Los Angeles whose work moves between material and light, the digital and the tangible. A website is already made of light, even when it is trying to behave like a neutral place to put photographs. Here, the light gets to be part of what you are looking at.

Move the cursor toward the dot at the center and his work gradually depixelates into view. A cursor is a peculiar substitute for a body. It can approach something without anyone leaving their chair. The movement is small, but it changes how much of the work you can see.

The dot stays with you as you move through the site, offering a glimpse of what’s on the other side of a click. Meanwhile, the color has a whole day to get through. A short visit catches a small part of that change; staying longer reveals a little more. There is always some of the website you are too early or too late to see.
