2 great examples I know of:

I think the basics will do for most people. I don't think you should spend much time on it and go with the style of the second. A simple list of skills, previous projects, basic mission statement, and method to contact you is all you need to get hired as an employee or contractor. References and your ability to sell yourself over the phone/in the interview is what will seal the deal.
If you are looking to showboat or are in a particular industry that lends itself to showing off skills on the site, there could be a place for a unique website like the first one I linked to.
Play to your strengths. If that's a couple stints at big name companies, discuss those a bit and segue into what you are doing now and looking for.
If it's open source contributions, immediately link to your top projects on GitHub/your profile there.
If it's interactive design, you may wish to have a video demo reel, and perhaps do something creative with the overall site, like the first site I linked to.
Good luck, and above all keep it simple.
A bad, hard to understand one is worse than none at all.
