If you're a Drupal developer and find yourself constantly referring back to the documentation when using some of the more popular variables for the system, you should check out this new wallpaper over on Smashing Magazine that will put that information at your fingertips.
In this post we release a yet another freebie: a Drupal Cheat Sheet Desktop Wallpaper, a desktop wallpaper that features most popular variables of the open source content management system Drupal. The wallpaper was created by Giovanni Scala for Smashing Magazine and its readers.
There's multiple sizes you can download for several of the popular resolutions like 1024x768, 1440x900 and 1920x1200. The cheatsheet describes the Page.tpl.php, Node.tpl.php, Comment.tpl.php, Nlock.tpl.php and Box.tpl.php interfaces.
