of the 1997 Arakawa + Gins: Reversible Destiny exhibition at the Guggenheim Museum SoHo (the accompanying book of the same title remains the most comprehensive collection of their work, and it incorporates the whole of the Arakawa/Gins book, The Mechanism of Meaning). The panels appear as a constellation of views concerning the nature of meaning that may be characterized as "holistic" or as entailments of a holistic view concerning meaning. To date, two editions of The Mechanism of Meaning have been made and many of the panels fuse collaged elements. In the years since Arakawa's and Gins's deaths, there has been a legal dispute regarding ownership of The Mechanism of Meaning between the Architectural Body Research Foundation and the Reversible Destiny Foundation. Reversible Destiny Foundation (1980s – 2010) Arakawa and Madeline Gins co-founded the Reversible Destiny Foundation in 2010, an organization dedicated to the use of architecture to extend the human lifespan. They have co-authored books, including Reversible Destiny, which is the catalogue of their Guggenheim exhibition, Architectural Body (University of Alabama Press, 2002) and Making Dying Illegal (New York: Roof Books, 2006), and have designed and built residences and parks, including the Reversible Destiny Lofts-Mitaka (In Memory of Helen Keller), Bioscleave House (Lifespan Extending Villa), and the Site of Reversible Destiny-Yoro. Designed in 1995, "The Site of Reversible Destiny - Yoro Park" was conceived as an "experience park" to reorient and transform visitors' understanding of their bodily relationship to the physical world. Flat, planar surface were removed entirely from the park, and instead Arakawa and Gins placed great emphasis on hilly, bulging surfaces that complicated how one walked around the park; spectators were encouraged to interact with the site as if they were toddlers learning to walk for the first time. Bioslceave House (Lifespan Extending Villa) (2000–2008) in East Hampton, New York encapsulates the philosophies Arakawa and Gins shared toward human mortality. The house's form is characterized by its asymmetrical, undulating appearance whose interior and exterior walls are each painted in over four dozen shades of vibrant hues. Ceilings and entranceways extend across varying directions and heights, either along straightened or curved edges. Similarly, windows and light switches are strewn along the walls at inconsistent heights. The floors are designed from hardened soil with rounded bumps atop their surfaces that slope at both slight and steep inclines; freestanding poles are included in multiple rooms to assist occupants to maintain
