Is it possible to create a parallax style template for Wordpress in Artisteer?
Yes, it's possible. The hard part is finding someone who has done it, finding a theme for it in Artisteer and so on. You'd have to do it yourself, but it's doable by just creating a longer design and putting in anchor tags and then making those anchor tags links or icons. What this might or might not do to SEO is another story. I've read of people using Artisteer to create themes like this, but can't recall the one or two I've read about here. You may want to search the forum for "parallax theme" or "infinite scroll" themes.
