Gawd I love Inkscape! Creating these was actually very easy and fun once I had picked up a paper texture and a paint splatter from cgtextures.com. I'll likely take another go at something similar with maybe a little calmer texture, like cracked concrete or plaster since the crunchbang text is a little hard to see in spots, but then again, it's supposed to be grungy right? ;)
