Ugly: Too many spaces, free lines and comments in the code, so that even a 4-line-code needs more than two pages. I mean, if I want to read a book, I won't choose anyones source code comments. Further I hate too long names for variables. Everything longer than 5 letters is crap.

A code is good (not to say beautiful :-)), when it looks easy and short, and when it's easy to read. Always try to solve difficult problems as easy as possible!
