To see the earlier graphics, click the link for 2018 - 2017 - 2016 - 2015 and to look even further back, even earlier.
This page of graphics begins with January 2019 and will have the latest graphics at the top.
All clipart on this page (excluding the circlular logic logo) may be feely downloaded and reused/remixed. Choose from two formats: png and svg. The SVG flavor is that of Inkscape, because that's the tool I'm still learning to use. If you choose the SVG format, you may open the file in an SVG editor like Inkscape to modify as you wish. If you only need a finished clipart, just use the PNG, though realize that it will not endlessly resize without loss of detail. Using the SVG file will allow you to export at any size you want.
To get the graphics for your own use, download them to your computer. Please do not link to the originals here. Right Click the appropriate download icon below the graphic you want. In the context menu which opens, choose "Save Link As..." (Firefox) or the equivalent choice in the context menu of your browser.
For PNG use this download link icon or this for SVG in the grid below.
The wide border graphics like this example (if any) will be at the bottom of the page.
