Here's another little gift to help fellow OS X developers whose design 
skills leave something to be desired: an application icon template.

This is a layered Photoshop 7 PSD file, allowing you to readily create 
standard application icons of the form shown below. You can 
<a href="http://www.scotlandsoftware.com/ftp/icons/app_icon_template.tgz">download the template here</a>.

 



Each of the three main visual elements is on a separate layer, with editable Layer Styles for the drop-shadows. 
Also included are layers with positioning guides for each type of element (main page, page 2 below, and tool). 
Thanks again to Michael for the <a href="http://disco.ucsd.edu/blog/computers/mac/programming/art/penRelease.html">fountain pen graphic</a>.



As always, enjoy.
