YY_ShockRing was designed to be a feature-complete
plugin for making rings. Blend modes, thickness, feathering, opacity; YY_ShockRing has it all. Use it for shockwaves, motion graphics, or anywhere else you need rings.
YY_Voronoi is a procedural texture generator which can be used as all sorts of textures, from terrain maps to water caustics to abstract backgrounds. By layering different Voronoi patterns, variations in complexity can be achieved.
