Seen some requests for people asking for WP themes to go with various niches. We all know that there just isn't a WP theme for every damn niche out there. So what you do is you stick with the TwentyTen or TwentyEleven theme (both come with WP by default). Then you simply hit Google images and search for your niche keyword. You should get a bunch of related images, just pick one and use it to change the default header on the theme. Of course this can be done with any theme that lets you change header image. Hope this helped.
