Elemental

Elemental is a creative app for VJs and anyone interested in generating (non-AI) visual imagery and patterns linked to music.  Through a complex but intuitive (and geekily fun) control panel, it provides (literally) endless ways of mixing images, external sources, animations, etc through a unique 3d particle system and effects deck, all of which can be fed out (via spout) into your favourite video mixing software for your final presentation. It's like milkdrop on steroids, but pre-2000s dirty oldschool steroids, before everyone starting wearing lycra.

The full version supports 4+ channels, Ableton Link, multiple spout output decks, midi mapping UX, dynamic 3d effects and much more. (A separate, free, watermarked, limited demo version is also available - please try this out before purchasing!).
