#8 well, josh, that's terribly poetic. i might have to read that to my students. :) and, i do know people who eat ferns... mostly not americans though. ok... to business...
I like the fern uncoiling. i personally would love to see that shape, somehow incorporated. - and the words 'be yoga' more set in an even easier font to read at a glance.
i'm also a fan of the nautilus spiral - would you consider one, confined in a sphere, with the words 'be' in the sphere, and the 'yoga continuing outside (the words in one horizontal line?
