Expandism is an art making style or method based on expansion. Expansion means that some phenomenon – like matter, people, nation, disease, ideology etc. – is conquering to itself more space. Expansion is evident for example in formation of cell tissue, which is based on the dividing process of cells. In art making there happens no this kind of dividing. Instead expansion is based on repetition of some artistic action – say, brush strokes – done by an artist. Repetition means that something that has been done earlier is done again.
