I found this at a brick & mortar store where the price was high. Amazon had it for a more palatable price so I picked it up here. The disk it comes with contains all of the many grids shown in the book in vector form and you are free to use them as you please. I've used them for fine art vector based illustration work and love the tangents these elements have taken some of my projects on.
-Try rastorizing one of these grid files in Photoshop, then applying filters such as twirl or other distort functions to them. It creates amazing and original visual effects. The higher resolution you work in in Photoshop the better the end result is likely to be.
-See my uploaded file for an example of what I did with a grid, placed into an illustration and distorted.
-Try enlarging a grid and using it as a template for a page layout, for alignment of elements on the page. Rotate it slightly for added energy swiss-style.
The printed book may seem like overkill, but it's indispensable as a quick easy way to locate a particular grid you'd like to use.
