The comic series Touhyou Rozen Manga (投票ローゼン漫画, or "Voting Rozen Comic") can be found at the Yudokuya Home Page (友毒屋hp).
Composed over a period of about a month, the artist drew one more page
in the continuing series every couple of days, with the story taking a
direction dictated by multiple-choice polls voted upon by the site's
visitors. This explains the somewhat random and unfocused nature of the
series. Still, there are a few funny gags here and there, as well as
some references to other web comics with which you may be familiar.
