Twizla

Twizla is a tool that creates displays with dynamic, evolving colours and visual effects, accompanied by music and sound. Twizla includes a variety of preset displays, and can load and play displays created by other users and distributed as Twizla files.
In some ways, Twizla displays are similar to the visualizations featured in some music players. However, visualizations tend to be provided as an optional, add-on extra, secondary to the music. With Twizla, the visuals are every bit as important as the sound.
The flickering patterns create a pleasant, strobe-like effect and can be enjoyed simply as entertainment. However, the flickering occurs in the same frequency range (1 to 20 Hz.) used to categorize electrical activity in the brain (alpha, beta, delta and theta waves), and one of the audio outputs is a binaural beat which tracks the flicker rate. Thus Twizla may be used as a tool to experiment with so-called brainwave entrainment.
Twizla is designed for entertainment. No specific claims are made as to the medical or other effects of running this software. Twizla does produce visual flickering that may be uncomfortable for some people.
NOTE: As with any source of flickering light you should be cautious, particularly if you:
ï¿­ have ever suffered from any form of seizure disorder or epilepsy,
ï¿­ have suffered serious head injury or concussion,
ï¿­ are taking psychoactive drugs (tranquillizers, stimulants etc.), or
ï¿­ are sensitive to bright or flickering light.
Limitations:
ï¿­ With the registered version you can also create your own displays, which can then be saved as Twizla files and exchanged with other users.
