Our logo is half a sun—symbolizing the fact that we’re halfway there. We have the technology that we need; now what’s required is political will. And that’s a resource we can summon! It would be a real help if you’d complete the drawing of a sun with the tools here, and then post it in our global gallery and share it online—we need tens of thousands of these drawings to form the backdrop for all we do going forward.
