Haruhi manages to blackmail a laptop off the Computer Research Society and have them set up a LAN cable between their club rooms, connecting them to the school's domain. Yay, internet. She then feels the need for an S.O.S. Brigade website, and appoints the troublesome task to Kyon.
Here is the initial S.O.S. Brigade website he came up with. Haruhi fround his layout boring, so she spiced it up with enticing pictures of Mikuru to bring more hits.
Here we see the updated version, with the S.O.S. Brigade logo - which Kyon thought looked like a drunken tapeworm. He also took down the pictures of Mikuru, and kept them in a folder for himself.
