Angklung is a musical instrument made out of two bamboo tubes attached to a bamboo frame. The tubes are carved so that they have a resonant pitch when struck. The two tubes are tuned to octaves. The base of the frame is held with one hand while the other hand shakes the instrument rapidly from side to side. This causes a rapidly repeating note to sound. Thus each of three or more angklung performers in an ensemble will play just one note and together complete melodies are produced. Angklung is popular throughout Southeast Asia, but originated from Indonesia (used and played by the Sundanese since the ancient times). Read more about Angklung v1.0 (iPhone misc)

The Particle Swarm Optimization (PSO) algorithm is classified as a population-based stochastic optimization technique. A set of potential solutions are evolved to approach an approximate solution (or set of solutions) for a problem. With PSO being an optimization strategy, the aim is to discover the global optimum that satisfies the constraints of the fitness criteria defined in the given search space for the problem. This application demonstrates how the Particle Swarm Optimization (PSO) algorithm works through the use of 2D visualization. By selecting and moving the large orange sphere in the application, blue particles will continually swarm towards it. Users can also alter the behaviour of the swarm by specifying the global best (gBest), personal best (pBest), and delta-time parameters and view their effects. Read more about PSO v1.0 (iPhone misc)

Do you have perfect pitch? Here's a way to both test your ear and train it at the same time. Pitch Hero plays you a note; you listen and then hit the corresponding piano key. If you don't get it right on your first attempt, you can peck around on the vintage grand piano until you're correct. You can measure your progress through a final score that measures both your time and the number of errors you make. Pitch Hero will sharpen your skills at both note and interval recognition.
