Obscure email addresses in drupal using signwriter

Signwriter is a Drupal module that allows you to use TrueType fonts to replace text in headings, menu's etc.
It does this by replacing text with an image from the TrueType font file. This enables you to obscure email addresses, by replacing them with an image.
