subflow vs Grating Simulator

Crisp visualizations for your music stage or living room. Tap left or right edge of screen to change modes. Vertical swipes change speed. Tap the upper half of the screen several times to set a beat pattern. Tap the lower half to cancel or to add single beats. Horizontal swipes fine-tune the beat alignment. Long press will change color. You can also send more complex command sequences over UDP, and you can control via OS2L using most DJ software. See http://subflow.org/

The laser interference pattern is similar to what would be produced by a Laser pointer’s beam passing through a diffraction grating – When you shine a laser pointer (green, 532nm wavelength) through a series of transmission diffraction gratings, you get a beautiful regular array of bright spots. The center spot is the zero-order (undiffracted beam), and the surrounding spots are the various diffraction orders. The symmetry and regularity of the pattern is characteristic of a diffraction grating pattern. This simulation could be used as a demonstration setup for physics education – teaching about wave optics, interference and diffraction. It is a classic physics demonstration that beautifully illustrates the wave nature of light and the principles of diffraction.
