This OMGWTF calculator was implemented without using the ++, --, +, -, / and * operators, while and for loops, and if statements that do anything more than goto or return (well there are a few exceptions, but that's just because nested, indented if-blocks look so damn sexy). Each of the 4 operations is implemented differently, each WTF-y in it's own way. All I can say is that it needs to be able to access www.google.com/search, and it uses calc.exe. The rest is in the readme and comments. Enjoy!
