It is important to have the science open to the public and those of limited access.
Additionally, one thing that I feel to have contributed nicely is creating a bunch of figures, logos, schematics, etc. Below you will see thumbnails for some of them (those that I am able to change and distribute under creative commons, and without breaking any licensing agreements). Clicking on the link will give you the original high-quality vector graphics .svg or .cdr file. Most of those have been also uploaded to the figshare, feel free to cite the .doi if you use the figure as is. Or, feel free to modify it to your personal use!
