I rather like this work by Jonathan Gillie. The Kandinsky like composition just seems to work really nicely. It reminds me of a series of works by Brandon Blommaert of geometric shapes changing colour and form to sound.
This is a stunning installation work called Oscillating Continuum, by Ryoichi Kurokawa, a Japanese sound and visual artist working in Berlin, Germany. The sound and the digital visuals combine beautifully and seamlessly with the sculpture. Really impressive work.
