Obfuscated C has been a hobby of mine since shortly after I started programming. I love looking at entries to the IOCCC. I have written my fair share of obfuscated code. Here's some:
This code prints out "ZACH" in big letters. 
char*c="(&$'&%$&$#'$&$&$&$$$&$#&$'$&$($&$#%$'$$$%$((#%$'$$$%$($&$#$$'($$($&" 
"$#$($&$$$&$$$&$#($$&$%&%$&$#",z,q=0,p=35;main(){for(;q<8;c++,p^=35){if(*c== 
35)++q&&puts("")&&(p=q<6?35:0);for(z=35;z++<*c;)putchar(p);}}/*Zach Wegner*/
