Who to Believe, a Giant Optical Illusion Outside Paris City Hall

“Who to Believe” by French artist François Abelanet is a large scale optical illusion installed outside the Paris City Hall. When viewed from a specific angle, the 100 meter long grass installation appears to be a much smaller three-dimensional sphere. This French language video by Paris.fr shows how the installation was built.
