After the hype that was going around about this effect I caved in a bought it. What I found myself
with was a PDF with a "few" pages. The main effect is not the effect you see in the trailer instead
the trailer shows the "bonus" effect.
Not only was the bonus effect explained in a
paragraph it was not in depth and rather vague.
If you think the trailer is too good to be
true... it's because it is.
