[8] In 2001 she had a solo exhibition at the Whitney Museum at Altria called “G-Force” for which Day suspended hundreds of resin-coated thongs from the ceiling in fighter-jet formations.

[13] A scale model of "Bride Fight" was later shown as part of the Peabody Essex Museum's "Wedded Bliss: The Marriage of Art and Ceremony" exhibition in 2008.

[14] That same year, Day had a solo exhibition of 3-D drawings in black light at the Santa Barbara Contemporary Arts Forum titled “Intergalactic Installations.”[15] Later that year she exhibited a sound installation in the Boiler Room at MoMA PS1 titled "Sweet Heat," featuring "speakers throughout the room that emit the sounds of cats purring, ... bring[ing] the space to life with feline activity.

[18] In 2010, she was awarded the Versailles Foundation Munn Artists Program residency at Claude Monet’s Garden in Giverny, France resulting in two solo shows.

“Seducers” at Carolina Nitsch Contemporary Gallery, where she presented high-resolution scans of the reproductive organs of flowers,[19] and at The Hole Gallery, where a recreation of Monet’s Garden was installed with living plants and a lily pond and photographs were displayed that Day made of punk legend Kembra Pfahler as her character The Voluptuous Horror of Karen Black commandeering the tranquility of Monet’s Garden.

“CatFight” was then exhibited at Mary Boone Gallery in her 2014 solo show called “Semi-Feral.”[21] In 2013, at Philip Johnson’s Glass House Estate, in New Canaan, CT, she was commissioned to create a site specific installation and exhibition called “SNAP!,” that featured heavyweight red rope nets enveloping and ensnaring the iconic “Da Monsta” building to the ground.

[23] In 2016, Day was awarded a Rome Prize fellowship at the American Academy in Rome,[24] culminating in an exhibition of her work, a suspended sculpture called “Golden Rays/In-Vitro.” The work was inspired by Bernini’s Ecstasy of Saint Teresa altarpiece and used gold-leafed aircraft cable referencing the raggi and golden rays depicted in annunciation painting and sculpture of the Italian baroque period.
