For the future DrupalCamp Lyon to be held in March, April 2012 (To be confirmed), I made some logos inspired by Lyon (city/animal):
There are 3 ideas and variations. For Sketch No. 2, the variations are mainly the drop on the forehead (with or without reflection), reflections on the upper face of the lion (maybe not very printer friendly), the white or dark mouth of the lion and white or blue edges (latest version at the bottom center).
You can vote for the logo you like better below. The poll order is the same as in the gallery.
Thank you in advance for your feedback and votes 🙂
