The art of the new millennium in many ways picks up where the last century left off. It is characterised by a great diversity of expression, materials and themes, and traditional forms of expression, such as painting and sculpture, exist side-by-side with media art, installation art and performances. Artists find their own expression by the combination of different idioms or by the use of non-traditional materials. For example, Tal R's paintings employ spray paint and pencil drawings, and Christina Hamre's sculpture The Uniformed Sleepwalker is made of felt, zips and buttons. Artists draw inspiration from art history, everyday life, technology, fantasy, popular culture and the city etc. From the 1990s onwards one notices that artists once again begin to deal with political and social issues. An example of this trend is the artist group Superflex, who spotlight issues such as the financial crisis, global warming and poverty.
