"It's sick as hell."
Uzumaki is a horror manga by Junji Ito that was published in Shogakukan's weekly "Big Comic Spirits", a seinen manga magazine in 1998. (Seinen just means that it is targeted to a male audience between the ages of 18 and 30.) It revolves around a small town that gets drawn in to a spiral obsession. Many different spiral obsessions occur that lead to a gruesome death for the subject. This image particularly demonstrates the first spiral death that occurs in the town. It displays just how powerful the obsession can be and what you can do visually with just the pattern of a spiral. The eye naturally tends to follow the pattern of a spiral and with the body in this image; the eye can see how his shape contorted to fit the pattern. The artist's intent with this image is to horrify, disturb and maybe even satisfy his audience. (To each their own yes?) Style wise, I feel it fits the seinen genre, since they tend to be darker drawings with less emphasis on typical "anime" eyes and other features. In terms of what it was made for, I believe it succeeded very well. It's mature enough both in its story and visualization to appeal to young adults.
In my opinion if you're into this type of stuff, it's great visual inspiration and a pretty quick read. You can find it easily online. I'd also say to check out the movie as well.
Here is one place to read it that I found to have the least annoying pop-ups and such: link
