1. obfuscated c contest
(in full, the ‘International Obfuscated C Code Contest’,
or IOCCC) An annual contest run since 1984 over Usenet by Landon Curt Noll
and friends. The overall winner is whoever produces the most unreadable,
creative, and bizarre (but working) C program; various other prizes are
awarded at the judges' whim. C's terse syntax and macro-preprocessor
facilities give contestants a lot of maneuvering room. The winning
programs often manage to be simultaneously (a) funny, (b) breathtaking
works of art, and (c) horrible examples of how not to
code in C.This relatively short and sweet entry might help convey the flavor of
obfuscated C:
/*
* HELLO WORLD program
* by Jack Applin and Robert Heckendorn, 1985
* (Note: depends on being able to modify elements of argv[],
* which is not guaranteed by ANSI and often not possible.)
*/
main(v,c)char**c;{for(v[c++]="Hello, world!
)";
(!!c)[*c]&&(v--||--c&&execlp(*c,*c,c[!!c]+!!c,!c));
**c=!c)write(!!*c,*c,!!**c);}

Here's another good one:
/*
* Program to compute an approximation of pi
* by Brian Westley, 1988
* (requires pcc macro concatenation; try gcc -traditional-cpp)
*/
#define _ -F<00||--F-OO--;
int F=00,OO=00;
main(){F_OO();printf("%1.3f
",4.*-F/OO/OO);}F_OO()

Note that this program works by computing its own area. For more
digits, write a bigger program. See also
hello world. The IOCCC has an official home page at http://www.ioccc.org/.
