Particle Generator is an attractive mod that provides you with one block. As the name says, it generates particles. You can choose the particle, position, velocity and arguments inside the custom GUI. Particularly, you should power the block to spawn the particles.
To craft the block, you need to put cobblestone at the sides, except the middle top slot where you put gunpowder and redstone in the center.
