The Red Serpent
Here's part of Gröna Lund, a relatively small but popular amusement park in Stockholm. Twister is one of seven roller coasters, a wooden ride opened just last summer. I'm not sure why I got the idea, but selective coloring worked rather nice here.
On an entirely separate issue, I've recently started publishing full resolution photos. Feel free to use them in any non-commercial way you like. I don't understand people who hide their EXIF, only publish stuff in postcard-size, or put distracting watermarks all over the place. Unless you're getting millions of hits, what are you compensating for?
