Truly Unique.
Every once in a while, something interesting - something unique will pop out at you. Now, Newgrounds may be infamous for its violence and humor, but every once in a while you'll come accross a gem such as "how it will end." Not only is it like something you've never seen, but it has amazing art and animation (whoever's seen "Waking Life" will know what I'm talking about), not to mention humor and great sound. An amazing compilation of ideas, thoughts, and experimental work to be seen.
