Elusive artwork that can only be seen at sunset
While staring listlessly at my bedroom wall once, I noticed quite a striking effect. It normally looks like a plain, white painted wall (which it is), but as the sun went down, for a few minutes it was shining directly along the surface of the wall. The angle of the light caused every tiny dip or bump
in the wall to cast a shadow, so every previously undetectable feature became highly visible. It was also quite a fetching fiery red colour, but I digress...
My proposal is to use this effect to make a mural which is only visible at sunset. At most times of day, the wall would look like a perfectly ordinary wall. But it is covered with tiles which have had a picture printed on them with tiny dots of enamel. As the sun goes down, for a few minutes every evening the dots are thrown into sharp relief and the picture becomes visible.

||I read about a bas relief of a similar nature, done on the outside of a building in Europe. See my annotation near the bottom of "Shadow Parks."
||This is indeed a cool idea. I did read
about a slightly similar concept in
wired/or tv. A video camera was hooked
up a computer and output to a
"monitor" made up of blocks of wood
that would rotate, thus changing, the
depth, color (something, I forgot). It got
the values from the RGB pixel values.
Very freaking cool.
||Someone did run around my little city
just the other day and drew outlines
around the shadows of objects in the
street. Perhaps this was you...
