Very easy to do.
Create 4 square planes and subdivide them. Eliminate some faces to model the planes with the shape of the letters. Extrude'em to give some depth. Search images for "black white pattern" on Google, choose one of them and use it for the materials. Add a beavel modifier to the letters. Once created the material duplicate several times the word and rotate it. Add a plane and place it above the letters, and add a particle system to it; Create a cube on another layer and give it the same material of the word, attach it to a group and set the particle system of the plane to that group, and leave it on emmiter. Simulate the particles.
For last, Give some mist to the camera, depth of field and render.
