  We present a novel real-time, collaborative, and interactive AI painting
system, Mappa Mundi, for artistic Mind Map creation. The system consists of a
voice-based input interface, an automatic topic expansion module, and an image
projection module. The key innovation is to inject Artificial Imagination into
painting creation by considering lexical and phonological similarities of
language, learning and inheriting artist's original painting style, and
applying the principles of Dadaism and impossibility of improvisation. Our
system indicates that AI and artist can collaborate seamlessly to create
imaginative artistic painting and Mappa Mundi has been applied in art
