"Infinity" is a software based Lucid Dreaming course: It's completely free and a clean download. Basically, over the span of a week (going one day at a time), the course will have you build up a repertoire that is supposed to almost promise you will LD at the end of the week. It's gotten a lot of great reviews so I figured I'd give it a shot. DV won't let me post a URL for it but if you search "lucid dreaming infinity" it will be the fourth result titled: "[software] Infinity - PDF Available"
