The imageboard 8chan is now known as the website where mass killers in New Zealand and El Paso shared their racist ideologies, but it didn't start that way. It began as a haven for free speech — or at least that's what its founder believed it to be. Cartuna created unique and graphically bold segments to punctuate Vice News Tonight’s special report on the complicated story of 8chan that premiered on HBO. Animation styles included 8-bit, anime, linework, and psychedelia.
