“If You Go Tweeting 4-Bit Grayscale Pictures of Chairman Mao…

…ain’t gonna make it with anyone anyhow.” After I did the CGA color palette, it was a no-brainer to do a 16-color grayscale version. Chairman Mao, before his tweet: (and bigger) And after his tweet: 102455300114B869D8304F53469AB36A23358AF53655579DC22364558D602334836D502456C7AD5014 67DBD9211356BBF81113AEFFCC40467FFDBED65778ABEED9 4bG 10×13
