Hello I will use this thread to post some images of experiments with Inkscape
i'm currently using only the unstable version 0.9x, some images were created only to test the gradient mesh tool like this first.
I made a short video without explanation, because the process is quite simple.

Pen tool, filters and gradient mesh only for the box.

An attempt to make a custom image of Jimi Hendrix using only pen tool and filters
