No kidding. As part of a mapping project I worked on, I created a set of 200+ custom SVG icons. I used Inkscape and hand-drew most of the shapes or modified existing glyphs from icon fonts or other raw vector graphic sources. This took months of work and planning, and I even figured out how to use Inkscape’s batch scripting API to automate some things. It was one of the most tedious things I’ve worked on and I am very proud of it. And as far as I know, it’s still in use today by the customer.
