MilkDrop is an advanced music visualization app (or website) created by the legendary music producer and software developer Ryan Geiss. It is an open source software that allows users to generate stunning visuals from any music file in real time. MilkDrop takes the music data and creates a 3D environment with various objects, shapes, and colors that move and interact with the music. MilkDrop is also highly customizable so users can tweak the visuals to their liking. It is a great way to add visual ambiance to any music playing experience.
