Even if we did use some form of wildlife, we'd still be copying Azureus' logo concept. It would also be an obvious attempt at that, since no animal really matches µTorrent's name while remaining easily identifiable as a suitable "brand" logo. We need something completely original, and as Determination says, it's not really possible now µTorrent already has such a prominent feature in its title... namely the "µ". What we need is someone to completely redesign an image based around the µ symbol from scratch, rather than just placing it inside a glossy sphere or square. The best candidates I've seen for this so far is MechR's arrow logo, BloodStaindHurricane's minimalist work on page 3, and Huck's square grid. In my opinion, however, none of these submissions are currently polished or professional enough for use at the moment.
