Icons can be helpful for providing visual cues for functions in user interfaces. But when you’re wireframing (creating user interface schematics), little blank boxes can be poor substitutes for communicating the purpose of the icon. This is a set of grayscale cursors and icons that come in handy when designing wireframes. The icons are designed to work well with your wireframe stencils.

This is a set of shapes for making wireframes (low-fidelity web page schematics) in OmniGraffle version 5.x (Mac OS X). It consists of most of the basic elements you’ll need to create user interface specifications.

Nice to see the effort that went into the design.
