Using Blend Tool on Illustrator

I have developed an understanding of how to use the blend tool in Adobe Illustrator using the tutorial from the A2 Graphics Blog, I found that this tutorial to be very simple once I got use to it. The word worked well with the Blends created and how they physically looked however, I prefer the way in which the technique can be utilised to create a 3D effect with the spirals. the stand out for me and this is  something I would like to incorporate into the background imagery of the type.
