New platform advocates positive change in the world through art and design

Founded last month by British creative Ellis Sargeant-Long, it's a site where you can submit your own poster design for people to download for free and to use at protests. Right now, the focus is on Black Lives Matter.

"We have had an overwhelming amount of submissions, but we'd love to get more creatives on board to help strengthen and spread the message even wider," says Ellis. "The artworks so far are a marriage of design and language that create impactful messages used to help amplify the voices of the people."

He adds: "Art and design have always been at the core of supporting global movements. Now more than ever, it can help aid, share and empower the messages of the Black Lives Matter movement to help bring about systemic change in our society."

Signs of Change features a PDF upload system to make it easy for anyone, anywhere, to get involved. The initiative will also showcase some of the best posters on Instagram. Current designs are from Christian Martinez, Lauren Martin, Jason Yun, Craig Berry, Laura Dietze, and many more. For more information, visit signs-of-change.com.
