Very Cool Letter Manipulation Logo designs

I've always appreciated logo designs that used letters as symbols and logo designers that transformed initials into iconic images through letter manipulation. Its always interesting to see letters taking shape of objects, living creatures or virtual imaginary icons through smart and creative techniques that logo designers use. The challenge when applying the letter manipulation technique to transform an initial into a strong symbol is to see beyond the primary shape of the letter and to find connections with the object you are trying to represent. I've made a selection of smart and very cool logo designs who's icons are obtained by transforming one or more letters into powerful and appealing icons that are fun and memorable, from cows and birds to ice cream and musical notes.
