Created by Matthew Davey, the Mercury Particle Engine is a fantastic free open source tool that comes equipped with a graphical particle effect editor. If you are looking for a good, fast and reliable particle engine; this is an excellent choice.
Owner of the Mercury Particle Engine project - first released back in 2006 and then refined over 5 major iterations to find the perfect architecture for the particle engine.
Joined the project in 2009. Wrote documentation and restructured the project to make it appealing for game developers. Now works as a developer on extending the capabilities of the engine. Ian is also the project lead on the brilliant Farseer Physics Engine project.
Joined the project in 2010, contributed multi-threading support and sample applications among other things.
Created the PolygonEmitter and TextureEmitter and contributed both to the MPE project. (TextureEmitter has now been replaced by MaskEmitter, however Alexandres code is still present)
