Make a pattered image like a brick wall look like text is popping out of it.
Tip:
Instead of popping out, you can make the text look like it's going inside the wall by by making the shadow thicker on top than on bottom.
This is a different and unique way to turn text into an Path, and draw it along a curved line using the pencil or pen tools. The technique can also be used with any other shape, like stars, spirals, or your own creation.
Mechanical gear shapes can be created easily in Inkscape. This tutorial will show you how, and give you an idea on applying filters to make the finished design look old and worn.
