Now you can add coffee stains to your LaTeX documents without wasting coffee:
Your readers will appreciate you saving them the effort. From the package documentation:
This package provides an essential feature to LATEX that has been missing for too long. It adds a coffee stain to your documents. A lot of time can be saved by printing stains directly on the page rather than adding it manually. You can choose from four different stain types:
1. 270◦ circle stain with two tiny splashes
2. 60◦ circle stain
3. two splashes with light colours
4. and a colourful twin splash.
