A long time ago, I set about creating a Photoshop Action that would make a selection (most likely a font) and make it look like it was made from a slice of Pizza. I posted an image made from that action an put it on my portfolio, with a brief explanation regarding its creation.
Recently, it appears that particular post has been getting a few hits. As it was only for my portfolio, there was no download of the action available. I have since rectified the situation. It is now available on my DeviantArt page. You can find the link here.
