Here are a few pages from my sketchbook. These are ideas for the OpenEZX logo.
Two recuring themes are emerging; a stylised penguin with beak pointing upwards whose belly makes the O in OpenEZX, and a blacked out logo with only the white of the penguin belly and eye surround and the yellow of beak and feet showing. Both incorporate the familiar radial lines signifying wireless.
