AcidWarp

AcidWarp is a 2D demo originally written for DOS in 1992 by Noah Spurrier and Mark Bilk. It periodically generated over 40 different patterns on the fly by plotting 2D mathematical formulas, and then animated them through palette rotation. It was notable for its speed on early x86 processors that lacked a floating point unit. It achieved this through the use of an integer approximation library for all mathematical functions. It has since been released as open source and ported to a variety of platforms, including FreeBSD and Linux through the use of SVGAlib.

AcidWarp was made made popular through a home made projector called [http://www.noah.org/acidwarp/warper.html The Warper] . This device operated through a fresnel lens mounted inside of a cardboard box which would be placed around a monitor.
