Fractal noise is a key component in the generation of procedural textures. It allows the same texture to be called up and redrawn again and again. Fractal noise is used to imprint a greyscale noise or interference pattern onto a layer that is then applied to the texture to give a ?random grain?.

Nails on a blackboard. It is an unbearable noise, one that sends shivers through anyone who hears it. But why does it do this, and more importantly, how can a virtual environment replicate the effect in any sound?
A novel and very practical use for an iPhone as an auxiliary hearing aid has been developed. The soundAMP program takes control of the iPhone, and essentially uses the in-built microphone to boost ambient noise levels.
Commercial aircraft are a problem when it comes to linking them to the wider sensor net - all external electronic communication flows through a single part of the nose of the plane. This must be precision manufactured to be defect-free, or moisture and heat can tear the signal apart. How then, do you guarantee it is defect-free?
