The main ones were motion blur and a layer mask to get rid of the parts of the blur I didn't want. To get the beams going in all directions, I added some white around the edges of the leters with the airbrush set to "dissolve" and used the radial blur on zoom at 100%. In the first example I also used the liquify tool on the letters before blurring them to get the "curtain effect". I also used an outer glow effect layer on the letters. The main thing to remember is that you want some dark streaks as well as light.
