We are looking for an icon to represent the concept of Open Education. The icon needs to match an existing icon that represents a related concept: Open Access -- which refers to free online access to scientific research. We love the Open Access icon (an unlocked lock signifying unlocked access to research) because the design is simple, versatile, and distinctive. We want our icon to be in a similar vein.
The Open Education icon should, naturally, be suggestive of the idea of Open Education, which includes free access to online books, open courses, and collaborative learning techniques. We're open to pretty much any direction you'd like to take it. Other Open Education-related logos/icons tend to gravitate toward book imagery, which we're good with so long as the design is sufficiently distinctive from generic book icons (in the way that the Open Access lock is distinct from other lock icons). We're also open to having the Open Education icon follow some iteration on the lock/key theme, so long as there's a twist on it that makes it more relevant to education. The only things we'd prefer to stay away from anything that focuses on computers/smartphones or graduation caps, and anything too complex.
We expect the Open Access and Open Education icons to be used side-by-side a lot, so they should look good together at the same scale. It's not necessary that the Open Education icon be the exact same dimensions, but it should stick roughly between the 2:3 - 3:2 ratio range so that it will look OK inside of a circle or square button.
We've included a few images of the Open Access icon for reference.
