User Interface stencils
Edward Anastas has put together a handy stencil composed of often-used elements in HTML and web page forms: radio buttons, checkboxes, combo boxes, entry fields and text areas. Nice looking and Aqua, to boot.
User interface elements for the Windows operating system, in case you have to design an interface where Aqua widgets are considered a strange and mysterious concept, and licking them is totally out of the question.
Use this stencil to represent words, ideas, and tasks arranged around a central idea.
Just a variety of line styles and colors, ready-made. Customize this with your favorite line-styles.
