This installation is called "Eggs", by Felonius Asparagus
Yearning to be discovered during your deepest desert wanderings, the Eggs offer you a comfy haven for a nap, conversation, or other intimate interaction.
Long exposure taken at night at 3am, under full moon light. You can recognize some constellations in the sky.
