What among hackers is called a

<a href="display-hack.html"><i class="glossterm">display hack</i></a>. Classical effects include “<span class="quote">plasma</span>” (colorful
|

mess), “<span class="quote">keftales</span>” (<tt class="literal">x*x+y*y</tt>
|
||
and other similar patterns, usually combined with color-cycling), realtime
|
||
fractals, realtime 3d graphics, etc. Historically, demo effects have
|
||
cheated as much as possible to gain more speed and more complexity, using
|
||
low-precision math and masses of assembler code and building animation
|
||
realtime are three common tricks, but use of special hardware to fake
|
||
effects is a <a href="../G/Good-Thing.html"><i class="glossterm">Good Thing</i></a> on the demoscene (though

this is becoming less common as platforms like the Amiga fade

away). </p></dd><dd><p> 2. [Finland] Opposite of <a href="dancing-frog.html"><i class="glossterm">dancing frog</i></a>. The

crash that happens when you demonstrate a perfectly good prototype to a

well-known case involving Bill Gates demonstrating a brand new version of a
