First up is a Coil tool I created that you can customize to your specification. This coil also has Dynamic features.
Second is a Domino Tool I created that will create however many Dominos with random numbers as well as being able to shape the roll of dominos however you'd like via a curve.
Third is a Tool that will fracture walls and make them dynamic for simulation purposes.
Last is a Maya Fluid project that involved creating a fire effect using maya's Fluid system.
