The artist's work is mainly figurative. In “No Boundaries” there is a series of five pieces with the zebra as a theme. During the process of creating the zebras, Joke discovered the stunning African adobe architecture of Mali, hence one of the zebra pieces contains some details of an adobe wall. Other pieces are inspired by cultural elements from Ireland, Syria, and France. In her piece Intercultural Ireland Joke made a connection between Celtic Ireland, Christianity and Islam, because in a relatively short time Ireland has changed to a multi cultural society.
