Extrude in Inkscape
To design the poster image for The People VS The Machine I revisited an old technique that wrote about in 2009. The technique used the Extrude extension in Inkscape, combined with the Color > Randomize extension to create what could be described as a stained-glass effect for text.
I wanted to do the same and create an extrusion between each letter of the title text. This, however, presented a few challenges. In versions of Inkscape up to 0.49 the extrude extension would only work on two selected objects. Even if you highlighted more than two objects the extension would only choose two of them to apply the extrusion to (I’m still not sure how it decides which two to choose). I could do this manually with each pair of letters, but this would take a long time and could easily get confusing!
