Calligram

A calligram is text arranged in such a way that it forms a thematically related image. It can be a poem, a phrase, a portion of scripture, or a single word; the visual arrangement can rely on certain use of the typeface, calligraphy or handwriting, for instance along non-parallel and curved text lines, or in shaped paragraphs. The image created by the words illustrates the text by expressing visually what it says, or something closely associated; it can also, on purpose, show something contradictory with the text or otherwise be misleading.
