Memorial is an installation based on blood samples donated to the artist by ten people over a period of two years from 1995 to 1997. Each sample was photographed and the resulting saturated colour 'portraits' were set in resin on limestone slabs. The work was first shown in St Mary's Cathedral, Limerick, Ireland, in EV+A 1998.

"Blood Cell Memorial is actually two pieces which comprise a series of framed portraits of magnified blood smears. As a protagonist, blood is loaded with significance. As well as being the central theme of Christianity, blood in the age of HIV and Aids is no longer a private matter between oneself and one's cells, but is public and political".
Angeline Morrison, The Sunday Tribune.

All of the people who donated blood for this project have died since it began in 1995.
