Fiona Grady creates site-responsive drawings on walls, windows and floors using sequences of dispersing geometric shapes. Her practice recognizes the relationship between architecture, installation art and decoration; often using traditional mediums, such as fresco painting and stained glass, in a contemporary context. She plays with light, surface and scale; each piece changes with the light of day emphasizing the passing of time and the ephemeral nature of the work. The artworks are imaginings of how light moves throughout a space, stretching and rotating with the throughout the day. However she does not seek to literally map light but instead create rhythms; the blocks of colour act as a vessel that pinpoints the viewers’ presence within their setting and allows them to contemplate their surroundings.The artworks for Art on a Postcard auction were created during the coronavirus outbreak in her self-isolation kitchen studio. They are inspired by the rainbows created by children for the windows of their homes. The rainbows are a symbol of hope, a thank to our carers and frontline staff.
