I can't even begin to explain these sites. They are a little trippy, loaded with Flash, and a whole lot WTF. I feel these sites are hanging out on the outer-most sections of the internet universe, and I've done my best to pull them all together for you. You may never look at websites the same again.
#1 Treasure Box
I'm still trying to figure this one out. I guess it's a game. I have only been able to do four moves before it starts me over. Very odd, but a little fun.
#2 Superbad
Almost like a choose your own adventure book. Just find a place to click.
#3 Sugar Free Ink
A little heavy on load times, this black-and-white site is confusing, but keeps you occupied with its random assortment of zaniness.
#4 SPIN
This one starts off seemingly innocent, but once you've clicked start, you'll see why it's on the list. Like the sites above, just look for a place to click.
#5 Samorost 1
Odds are, you've seen this one before. I remember finding this site about a year ago, but it fits well on this list.
#6 Neave
This one looks like any standard flash-based site, but as soon as you start clicking, you'll realize you're wrapped up in the mind of Paul Neave - an interesting, scary place.
#7 ertdfgcvb.ch
Even the name is odd. This site has tons of random items to explore.
#8 Zoomquilt 2
I think I've seen another version of this, but this one seemed better. It's like going into a picture, but never stopping. I have no idea how they do this, but it's incredible.
#9 Boohbah Zone
Like the Teletubbies on acid. This is a very uncomfortable site.
#10 Medijate
This site is supposed to promote meditation, but its creepy music, frightening graphics, and odd mouse-following behavior will do anything BUT leave you feeling relaxed. The music is repetitive and annoying, but the visuals will keep you busy.
Know of any other sites that belong on this list? Let me know in the comments.
