Well, I made this simple program, which is not complete yet, but any suggestions of improving code would be great :)
Anyways, I'm mostly posting here 'cause I need to transfer the code, now that I don't have access to my home PC :/ oh and I do know that the code should be seperated into files, but I'm too lazy to do that :P
