When asked to create a 2D logo of a woman in warrior pose holding a Lotus flower, Robert Peake decided to use Blender. He describes the process of its creation on his website.
My sister asked me to design the logo for her website. Her vision: a woman in warrior pose holding a lotus in her upturned palm. My immediate thought: why not use Blender? After all, I had some success playing with existing logos earlier.
[...]There's no doubt that the flexibility of a 3D object and the ability to reposition both poses and camera angles at will came in extremely handy in designing this 2D logo.
Robert also created a logo animation for his employer, the DavidAllen company. This particularly caught my eye as I use their methodology, 'Getting Things Done' all the time to manage my work!
