Magnetic Flow is a visual app that uses physics and graphics techniques. The physics in this app uses Coulombs Law. Similar to poles for magnets it either attracts or repulses points based on touch. It uses alpha blending and has tracers that are offset from the original position using a distortion map.

Touch up to four fingers to change the paths of the magnetic poles. Single tap to change the type of point sprite. Double tap for new colors and a new distortion map. Triple tap to snap a portrait or landscape high resolution photo.

Make a game out of it, try and get all the particles to overlap. It is possible.

Enjoy!!!
