Here's an idea I have for a t-shirt logo for our church's youth group. I don't know if the youth group leader will like it, but it's totally my style. I probably could have used a fancier text (I used Impact), but it's highly readable and stands out as well as I can make it.
I created the texture as a grayscale image in Photoshop, opened it in Illustrator, then changed the colors (Filters/Colors/Adjust Colors) to whatever I wanted once I had the texture masked behind the text and background oval. The lightning Z is a couple of blended shapes. :)
