of these recent additions, I like #53 and #58 the best. I am still very concerned about the similarity to the Pepsi logo. Also #53 reminds me of a Pokemon ball (see:
http://www.russellheimlich.com/blog/wp-content/uploads/2008/09/poke-ball.jpg) another connotation I would like to avoid.
Some ideas:
- perhaps the 'sun' shape could break the boundary of the outer circle?
- you could try variations of the 'wave' shape to avoid similarity to Pepsi logo
- perhaps a variation in a square instead of circle?
I like the direction of this concept, but I really cannot use it if it immediately looks like a Pepsi logo
