In 1991, before the start of the Fall semester, I drew up a proposal for my year-long student project: to trace out the sun's analemma by following the shadows cast upon the SFAI student quad. Although Paul Kos, my teacher at the San Francisco Art Institute, very much liked the idea I proffered, he proposed another project of his own: to learn Spanish together with him. My idea was quashed as we set out to learn Spanish after hours, and I never did get to perform the analemma.
Here below is that very artpiece submission I put forward to Paul.*
As I was coming up with the idea, I thought surely the notion of recording the shadow must have occurred to others, but I never saw such a timelapse captured.
It would be that way for a great while.
Finally, in 2024, nearly thirty-three years later, someone, a certain Nick Wright of Falcon, Colorado took note of his driveway shadow as taken by his security camera. Voila! On November 29th, 2024 NASA's APOD (Astronomy Picture of the Day) posted Wright's inverted "Driveway Analemma" on their YouTube Channel.
Again, the decades long wait is not to suggest that no one else had ever thought to document the aforementioned shadows before me or since. I merely say, that in my case, it took that long at last see it so recorded by another.
*ADDENDUM: Just to make the original 1991 proposal a little easier to visually follow, I added in some shading. Here it is with the building shadows in place.
