Coffee diagram follow-up
Mugs, t-shirts, and source files now available
If you're simply looking to print up a copy to fold up in your wallet, I've created a PDF file which contains all nine images.
If you'd like to extend or localize the illustrations you can grab the Adobe Illustrator source file. You can also open up this file in Adobe Photoshop, without the vector data, as a bitmap..
I'm offering the illustrations under the Creative Commons Attribution-NonCommercial License. What this allows for is the use and modification of the work for noncommercial purposes. I chose a non-commercial license because I do not want people to sell the image. If you want to use the image for educational purposes in a commercial space such as a website or cafe, you have my permission to do so. As for attribution, I ask that you leave my name and website address in the fine print.
