Zip ItLogo Design Contest

I like this concept...is there a way to include idea of zipper teeth?

Thanks Sromek. #74 zipper attached. Whole design forms a diamond-shape.

#76 Another version.

#77 Zip it zipper.

#81, #82 & #83 new zipper shape.

#84 zipper/speech bubble effect.

#85 Modernised version of zipper.

#123 Alternative from the ZIP-style, concentrating on the writing-aspect. Pencil writes a large 'Z', which doubles as a path of transference and communication.
Let me know what you think, Sromek.
