Mac OS X 10.0 Cheetah
The fastest over land (it’s the fastest land animal), it’s still spotted (it has spots on its coat) in Iran (the last refuge of the Asiatic Cheetah), and debuted twenty years ago (it was released 20 years ago, on 24 March 2001).

Inferno
Out of Plan 9 (the name of the OS from which it’s descended) came the first hellish book of the best-known comedy (‘Inferno’ is the first book of Dante’s trilogy ‘The Divine Comedy’), as an operating system (Inferno is a distributed operating system, whose names are all inspired by Dante).
I look forward to your putting alternative cases.
