For centuries, artists, philosophers, and scientists the world over (among many others) have pondered the concepts of illusion and reality. The art exhibition Illusions, presented at Rio de Janeiro's Casa Daros in 2014-2015 and viewable in digital form here, offers ten artists' explorations of "the ambiguous and complex, difficult to interpret spaces that swing freely back and forth between a supposed reality and so-called illusion." This mesmerizing exhibition's web experience is interactive and best viewed on a larger screen--as viewers scroll through the different works of art, many of the exhibits give the perception of three-dimensionality (without the need for glasses), while others use video along with still images. Illusions features artists from all over Latin America, and each artist's exhibit has an English-language PDF brochure available to download on the "Exhibition" page (accessible via the menu on the upper right). The exhibition was curated by Hans-Michael Herzog, founding director of Casa Daros, and art historian Katrin Steffen.
