Glitch art purists will insist on a distinction between art that uses actual malfunctions and art that imitates malfunctions. Daniel Temkin’s 2011 “Dither Studies” falls squarely in the former category, even though the program he’s created results in some fairly controlled experimentation. While we’re used to seeing dithering in GIFs resemble soft visual pixelation noise, here, Temkin runs two opposing colors through a dithering algorithm that creates harsh, grid-like forms.
Since the tool only employs three variables—two colors and a slider—the results are always the same. This stands in contrast to his “Glitchometry” project– in which Temkin sonifies a square or circle (runs it through a audio editor)– the results are wildly unpredictable.
Anyway, you can try the dithering algorithms here. You can even save the images for your own GIFs.
