I am, when I get around to it, planning to create a website for my university film-making society, and thus am in the process of learning basic HTML and web-building. If I can master that skill then I'm considering charging people to build websites for them and act as webmaster, and turn a decent skill in to something marketable.
Also, when I get the time and inclination to carry on, I am planning to write the rest of a Halo fanfic I started. The basic idea is that it's set just after, and a few years before, the events of Halo: Ghosts of Onyx, and details a mission that went wrong for Tom and Lucy (SPARTAN-IIIs of Beta Company) and how they're remembering it in the aftermath of entering the Onyx Dyson Sphere, while Tom tries to finally get Lucy to talk again. The first chapter is up on Fanfiction.net, and here is a link if anyone wants to read it. It is good, I promise, unlike most of the stuff on that site (in Sturgeon's Law, I come under the 10% of good stuff...).

Also planning a Higurashi no Naku Koro ni fanfic, writing an entirely new story arc based partly on Watanagashi-hen but with Mion going crazy instead of Shion, after some minor changes to the other arc events and Keiichi returning Rena's feelings instead... And I'm joining the Assassin's Society at university, and would love to do a proper LARP event at some point...
If those things don't make me enough of a geek, I don't know what will...
