Check out this installation made by DAKU, an anonymous artist from India. The installation, which is a quote from William Shakespeare, is activated by the sun; as the latter casts light on the installation, shadows are cast, and the quote appears.
The somewhat decontextualized phrase could reflect on time in general, or perhaps life itself. As the sun shifts throughout the day and casts its shifting shadows, the message appears and disappears, with the physical white letters blending into the building.
This is only one of the many time and light-activated installations of DAKU, which he refers to, collectively, as “Time Changes Everything.”
