Years ago, I stumbled across a Photoshop action that could make type look like it was made of pizza slices. Being too cheap to buy it, I set out to make one of my own. The results of my labour as seen in the image above. Even the placement of the pepperoni is handled automatically by the action.
The other Photoshop action I mentioned earlier has since been released as freeware, but I prefer mine.
EDIT: This post actually gets quite a few hits. Since there appears to be some sort of demand for this action, I’ve released it over at my DeviantArt account. Follow the link there.
