This is amazing to me. Via the Web site:
The results of an extensive exploration with shadows, the One Day Poem Pavilion demonstrates the poetic, transitory, site-sensitive and time-based nature of light and shadow.
Using a complex array of perforations, the pavilion’s surface allows light to pass through creating shifting patterns, which–during specific times of the year–transform into the legible text of a poem. The specific arrangements of the perforations reveal different shadow-poems according to the solar calendar: a theme of new-life during the summer solstice, a reflection on the passing of time at the period of the winter solstice.
I'd love to see this.
