Topoline Variable Font Collection

A variable display typeface from That That Type that moves along an axis from hollow outline to solid fill, with five named stops including Negative, Light, Empty, Bold and Full.
About
Rather than varying weight in a conventional sense, Topoline uses its variable axis to shift between different states of fill, from a reversed or negative treatment through to a completely solid letterform. The five named styles give designers distinct visual registers within a single font file. Coverage is limited to basic Latin, numerals and general punctuation, placing it firmly in display and titling territory.
Classification
Topoline is a variable display typeface with named stylistic extremes ranging from Negative (outline/reversed) to Full (filled), suggesting a geometric or constructed letterform approach used primarily for titling and expressive work.
