If a picture's worth a thousand words, an oil painting has to be worth a few hundred more. At least oil paintings created with Tyree Callahan's Chromatic Typewriter which lays down different hues of paint instead of letters.
Built for the 2012 West Collection competition, Tyree replaced the characters on the ends of the typebars with small pads of oil paint, while the letters on the keyboard were swapped out with color swatches indicating what hue would be laid down with each key press, including shift options.
While the hardware is decidedly old-school, the paintings are created in a fairly modern fashion, with each key producing a rectangular pixel of color. It's not unlike Seurat's style of painting, except that you can probably still get away with undoing your mistakes using a dab or two of liquid paper. [Tyree Callahan via Make]
