Thanks! I made it myself with 0-5% CP!
And about the GIMP thing: Id say make a new layer, make it transparent. Then to get the straight lines, use the Bexier tool(B) and use the curves to go over all the lines. Then got to Stroke from path and enter, say, 3px. It will leave a 3px line all over it. The one disadvantage is that near some anchors the lines will be slightly broken. Yu have to fix those yourself
