This is amazing..! Extremely clever. Using a complex array of perforations, light passing through the pavilion’s surface produces shifting patterns, which transform into the legible text of a poem.
The type is formed through a complex array of perforations aligned with the passing of the sun. The poem takes about 8 hours to sweep through the full text. Based around the solar calendar, winter and summer display different poems.
Check out the timelapse video. It’s fantastic.
