Her studies of organic growth, including shells and flowers, helped her portray life through a spiritual lens. Her individual or signature style was also marked with impressions from the late 19th and early 20th century scientific discoveries as also influenced by contemporary spiritual movements such as theosophy and anthroposophy too. The idea to transcend the physical world and the constraints of representational art is visible in her abstract paintings. Her symbolic visual language has an ordered progression that reflects her understanding of grids, circles, spirals and petal-like forms—sometimes diagrammatic, sometimes biomorphic. Her paintings also explored dichotomy of the world. Spiral forms appear often in her art, as they do in the automatic drawings by De Fem. While every such geometric form, in this case, Spiral suggests growth, progress and evolution, color choices also are metaphorical in nature. As one of the Proto-Feminist Artists, her style represents the sublime in the art. Legacy In her will, Hilma af Klint left all her abstract paintings to her nephew, vice-admiral Erik af Klint of the Royal Swedish Navy. She specified that her work should be kept secret for at least 20 years after her death. When the boxes were opened at the end of the 1960s, very few persons had knowledge of what would be revealed. In 1970 her paintings were offered as a gift to Moderna Museet i Stockholm, but the donation was declined. Erik af Klint then donated thousands of drawings and paintings to a foundation bearing the artist's name in the 1970s. Thanks to the art historian Åke Fant, her art was introduced to an international audience in the 1980s, when he presented her at a Nordik conference in Helsinki in 1984. The collection of abstract paintings of Hilma af Klint includes more than 1200 pieces. It is owned and managed by the Hilma af Klint Foundation in Stockholm, Sweden. In 2017, Norwegian architectural firm Snøhetta presented plans for an exhibition centre dedicated to af Klint in Järna, south of Stockholm, with estimated building costs of €6 to 7.5 million. In February 2018, the Foundation signed a long-term agreement of cooperation with the Moderna Museet, thereby confirming the perennity of the Hilma af Klint Room, i.e., a dedicated space at the museum where a dozen works of the artist are shown on a continuous basis. Cultural references Hilma af Klint and her work are presented in the movie Personal Shopper,
