Unique Forms of Continuity in Space is a bronze futurist sculpture by Umberto Boccioni. This is seen as an expression of movement and fluidity. Boccioni had a short, but productive life. The Futurist movement was striving to portray speed and forceful dynamism in their art. His sculptures were based on the energetic movements that symbolized the modern machine age. I love this sculpture and the representation of machine. It gives you the illusion that the sculpture is moving in fast speed.
