What are some good resource for programmers to design icons?
I have been developing web and iPhone applications for our company to use internally. For the artwork I've been using Procreate Inkpad and Sketchbook on my iPad and Inkscape and Gimp on my Mac.
I'm wondering if there is a simpler package. I'm, for the most part, only designing icons that the user clicks on.
If the tools I'm using are sufficient, any reference material for creating decent artwork, for the usage I have outlined, would be greatly appreciated.
