Concrete poetry

Sigrid
Wikipedia - "Concrete poetry or Size poetry is poetry in which the typographical arrangement of words is as important in conveying the intended effect as the conventional elements of the poem, such as meaning of words, rhythm, rhyme and so on. It is sometimes referred to as visual poetry, a term that has evolved to have distinct meaning of its own, but which shares the distinction of being poetry in which the visual elements are as important as the text."
