Thinking about fog. Starting with my code that fades out the foreground based on the depth data, I modified the script so that there’s some randomness to the transparency. I want the edges of the object to shift in and out, as if in a fogbank. But the effect needs work, and I didn’t get any good images today.
I spend a lot of time remembering. I scribble lists of what to try next, I keep track of my hours, I write blog posts about what I’m working on. My code is strewn with comments and reminders. I save drafts and sketches, I backup my work. The computer is a machine for remembering.
It’s easy to forget how useful forgetting can be. If I’m stuck on something, especially when writing code, most of the time I just need to get away from it for a while. In the movie True Stories, David Byrne’s character says something that’s stuck with me for years:
I really enjoy forgetting. When I first come to a place, I notice all the little details. I notice the way the sky looks. The color of white paper. The way people walk. Doorknobs. Everything. Then I get used to the place and I don’t notice those things anymore. So only by forgetting can I see the place again as it really is.
Forgetting, not only as a creative strategy, but as a pleasure. A way to recapture the joy of experiencing something for the first time. This came up again in a book I just finished, Michael Pollan’s The Botany of Desire:
Memory is the enemy of wonder, which abides nowhere else but in the present. This is why, unless you are a child, wonder depends on forgetting – on a process, that is, of subtraction.
When I want to wonder, I read anything by Italo Calvino. His final, unfinished book, Six Memos for the Next Millennium, is a series of lectures about various qualities he valued in literature. He starts with “lightness”:
My working method has more often than not involved the subtraction of weight. […] Above all I have tried to remove weight from the structure of stories and from language. […] Maybe I was only then becoming aware of the weight, the inertia, the opacity of the world – qualities that stick to writing from the start, unless one finds some way of evading them.
To erase the opacity of the world, what an admirable idea! I want my little fogbank script to attempt this. By erasing information from the video stream, by subtracting opacity, I can introduce a kind of lightness. An opportunity to see something as if for the first time.
Feet are good tools for forgetting. When I need a new perspective, I walk up Signal Hill, often along the North Head trail. I was up there once last summer, soon after I first moved here, and there was an incredibly dense fogbank hovering just off the edge of the cliff. I sat down and watched it for a bit. A kind of brilliant backlit haze, and peering into it felt almost as if my eyes were closed, but white instead of dark. After a while, I realized I could see something shifting around in the haze. It took me a minute to figure out what I was looking at, and I’m still not entirely sure if it was my contact lenses, or the inside of my eyes. But my vision was full of subtle little squiggles and inconsistencies, and if I moved my head they would swish from side to side. Entoptic phenomena.
The idea of seeing things with new eyes is present right in the title of Lawrence Weschler’s Seeing Is Forgetting The Name of The Thing One Sees. Near the end of the book Robert Irwin rants a bit about getting away from screens, something else I should try not to forget:
The point is to get people to peel those visors off their faces, to remove the goggles, to abandon the screens. Those screens whose very purpose is to screen the actual world out. Who cares about virtuality when there’s all this reality – this incredible, inexhaustible, insatiable, astonishing reality – present all around!
