Tsukichan
Also based around Serial Experiments Lain. A kind of odd cult that believes committing suicide will transport them to "The Wired", essentially a fictional form of the internet. I don't know, it's a weird one.
Sushigirl
Not really sure about this one but it's chill.
Danger/u/
An identical recreation of the fictional board in the game VA-11 Hall-A.
I've always wanted to see ssh take over the net. It's funny how we have these public file shares over web. If someone was brave enough they could just make a mountable ssh where each user had read access to the others.
