Hi everybody,

few ideas I spotted on the so far submitted logos inpired me to create also some proposals.

All logos are carefully designed to meet the following requirements.

* Support B/W rendering "out of the box" (just use e.g. the indexing algorithm in Gimp) * Be decently well readable * Be moderately intuitively understandable * Be compact in size, but not overly dense * Stay consistent (all components of the same importance shall have roughly the same visual area, size, color, and "shape kind") * Support future numbers in place of 68 * Favicon shall well resemble the logo (in this case the favicon will be a green character E) * The minimum safety zone does not need to be very big to let the logo be readable

Unfortunately I again ran out of my time to contribute to this interesting project. I might find some time later (in few months rather than weeks). So feel free to modify the logos to your needs. There is one more idea from my side - add a leaf of a lime tree (as it looks a bit like a heart) to make it less "technically" looking and more resembling the eco-friendliness.

Note, the attached bitmap exports are not perfect as the source SVG files are prepared for easy editing, but not for high-quality bitmap exporting with antialiasing. The source SVG files are Inkscape SVG files, so they are not optimized for viewing.

Cheers!
