The chedi (fig.) of Wat Phrathat Lampang Luang in Lampang reflected in reverse on the inner wall of the temple's mondop, by the sunlight that penetrates through a hole in the wooden fronton above its door (fig.).

This phenomena, known as camera obscura, is also found in the temple's Vihaan Phra Phut (fig.), where the chedi reflects on a piece of cloth through a crack in the wooden sidewall of the edifice.
