The works' environmental scale, its existence in public space, and its interactive structure are a few marks of Alessandrini's work.
In 1995, with Art In The Park, Alessandrini took advantage of her studies on natural phenomena such as light, shadows, and reflections and used them to provide an ordinary natural background and relative darkness for an outdoor site-specific video installation. The project won her a NIAUSI fellowship and the design was presented in a lecture format at the Seattle Art Museum in 1966.
In Winter, Season Of Light (2000), Alessandrini designed and built a virtual landscape that stretched 700 feet long and 100 feet high built of panels, light, and water to reveal the absent life and the physical void left behind after the demolition of a section of downtown Tacoma.
In Seattle, she also designed and built Aqua Pura Vista (2000), a light, video, and sound installation that occupied an early 20th century water tower in Capitol Hill. Natural sunlight and shadows cast patterns on the installation, already a digital representation of the surrounding nature and architecture of the tower.
