The Brainwave Visualizer is an Android app developed by NeuroSky Dev that allows you to control an interactive application with your brain. This app shows a colorful graphical representation of your brain's activity. The Brainwave Visualizer features Brainwave Visualization, Brainwave Power Spectrum Graph, and the eSense Attention and Meditation meters. The shapes on the screen change color and morph according to your state of mind, giving an interactive experience. It also allows you to listen to music and watch how your mind experiences the melodies.

One thing to note is that the Brainwave Visualizer requires a MindWave Mobile to function. Overall, this app is an interesting and unique way to interact with technology and explore your own mind.
