Medium

Ideas about the term "Medium".
When I thought about Medium, I immediately thought about my art practise -what is my medium? Initially I time-based sculpture, body performance, situation and object, object and architecture relational aesthetics...came to mind. I find it difficult to define my medium because my practise blurs the boundaries between traditionally defined self enclosed mediums such as sculpture, performance, photography, painting.
