Moshtube is an interactive, browser-based video synthesizer and VJ tool that allows users to remix and blend dual YouTube video streams in real-time. Built as a creative coding experiment, it features a custom "mosh" engine that applies dynamic SVG filters and CSS blend modes to simulate glitch art, analog signal degradation, and psychedelic visual effects. The application supports granular control over video looping, playback speed, and layer opacity, as well as a "chaos mode" for randomized procedural generation of audiovisual scenes.
