forty four flowers is a sound piece for mab macmoragh's sim eryri, and has also been shown at the artificial lawn of brooklyn is watching (mentioned by jay in a comment to this blog, but erroneously attributed to another work, see other comments). invisible moving sound sources play the names of forty four flowers, whispered by two different speakers. the visitor is confronted with the contradiction between the simulated environment, the invisible whispering human voices, and personal memories evoked by the flower names.
voices by amy freelunch (amy wilson) and arahan claveau (steve millar). arahan also made a video (well, more a sound recording) of it, see it here.
