Designed in 2011 and appropriated, with permission, by Extinction Rebellion in 2018 the XR logo is dramatic in its form-language, employing an hourglass motif to signal the imminent threat climate change poses. That this also forms an X and placed within a ‘globe’ reinforces a collective urgency. Elemental forms and a consistent line weight offers an exceptional functionalism, capable of being drawn by hand from memory, or rendered any number of ways using formal or free-form reproduction techniques, with an impact either scaled up or scaled down.
