The text brush lets you create visual art using words. You can change the text and font from the bottom bar, and you can also set whether or not the text repeats itself continuously. When you click the font button, you'll be prompted with a modal that contains an extensive list of fonts to choose from! The sample text will update based on the font you select, so you can get a sense of what you'll be painting before you paint it.
As an example of the great things you can create with this tool, you can check out mudimba's I Have A Dream, or watch a redraw of mudimba at work creating art!
