German artist Martin Klimas set out to answer the question "What does music look like?". In order to find out, he selects some music, puts splatters of different colours of paint on a translucent sheet over the diaphragm of a speaker and then turns up the volume.

The vibrations of the speaker send the paint up into the air, creating beautiful patterns and sculptural forms, and Klimas photographs the results. He typically chooses dynamic and percussive music such as Steve Reich, Miles Davis or Jimi Hendrix.

Photographer Tom Ryaboi is one of the crusaders of Rooftopping. The 27-year-old, from Toronto in Canada, has climbed more than 100 buildings and produced some of the most stunning examples of the craze. Rooftopping is the heart-stopping photography movement which involves thrill seekers climbing to the top of city skyscrapers, hanging off the edge and taking pictures of the spectacular view.

Tom Ryaboi said: 'It's addictive and I am always looking for a higher roof in the city. But I still feel the buzz whenever I reach the top and feel the wind. It's a pure rush of adrenaline.'I try to blend in as much as possible. In an office building I dress like I work there, on a construction site I dress like the workmen'.

'It's in my blood. When I was a child one day, my dad came home from work and found me sitting on top of the fridge.They had no idea how I had got there, but obviously I just liked climbing things.'

A drop of liquid explodes into a multicoloured splash in these pictures taken at a ten thousandth of a second by photgrapher Jim Kramer.The photos were captured using a timer which tracks the path of falling drops.With amazing accuracy a flash set off at the exact split second captures the water on impact.IT manager Jim Kramer used water and cream, coloured with food dye to create the eye-catching scenes.

All of the pictures were taken in the basement of Jim's home in Cincinnati, Ohio. Using an underwater pump linked to the timer, he was able to shoot a jet of water into the air to collide with the falling drop
Jim Kramer: "The picture of the multicoloured droplet was created by putting food dye on a blob of cream. I then released a droplet of cream onto that and caught it on camera as it exploded''.

Richard Shilling's land art involves making sculptures using only natural materials gathered near to where the sculpture is going to be made. He doesn't use glue or string and some of his work will last only a few short minutes before a change in the weather will sweep them away. Some of his art consists of different sized rocks balanced on top of each other precariously.

Richard, 39, draws his inspiration from fellow land artist Andy Goldsworthy. He accidentally came across one of Goldsworthy's sculptures while he was walking through a forest in Lancaster. He said: "I was walking on the hills near where I live and discovered an Andy Goldsworthy sculpture in the middle of nowhere. I was intrigued so I starting researching Goldsworthy's work and eventually started to make my own sculptures and ephemeral work a year later."

Miniature cars move along the elevated freeway at Chris Burden's large-scale kinetic sculpture, Metropolis II, during the media preview at the Los Angeles County Museum of Art in Los Angeles, California January 11, 2012. The sculpture, modeled after a fast-paced futuristic city with 1,100 miniature cars running through an elaborate system of roadway tracks at a scale speed of about 240 miles per hour (386 kph), is meant to evoke the energy of a city. The exhibit opens to the public January 14.

Yayoi Kusama is one of the most exciting and prolific artists working today. With a practice encompassing performance, film-making, painting, drawing, sculpture, installation, fashion, poetry, fiction and public spectacles over some 60 years, this leading Japanese practitioner has been widely acknowledged as a major influence on several generations of contemporary artists.

Art attendees were invited to transform a completely white gallery space with colorful dot stickers. 'The Obliteration Room' is part of the exhibition ‘Yayoi Kusama: Look Now, See Forever’, a survey of the artist’s current practice showing at the Gallery of Modern Art, Brisbane, Australia until March 11, 2012.
