Interfaces of 1989 Edition & 2017 Emulation of Hyperbola
Stuart Moulthrop's Hyperbola: A Digital Companion to Gravity's Rainbow (1989) represents a lossless type of migration. As a purely digital work that combines text with visual elements and animation, yet does not employ sound, it looks and behaves almost identical both in its original version for Macintosh computers and in modern emulation environments, such as the Internet Archive’s Software Library: Macintosh.
Hyperbola was created in Apple HyperCard software. Another of Moulthrop's HyperCard works, Dreamtime 3.1 (1992), apart from using even more animation and dynamic text effects, employed sound effects that do not appear in the emulated Web version. As such, Dreamtime represents a "lossy" type of migration.
