Illustrations that I have added to Wikimedia Commons and inserted in some articles:
Illustration of the electric field surrounding a positive (red) and a negative (green) charge (click for larger image). I inserted this illustration in the Electric field article.
Illustration of the electric field surrounding two equal charges (click for larger image).
Illustration of the electric field surrounding one positive charge (click for larger image). I'm not quite satisfied with this one, but I don't see any article where it would be obvious to use, so I won't improve it just now.
You know normal links—they look [[like this]]. But did you know that you can use normal links to pages on any other wiki? This is called InterWiki linking, and applies to all wikis, not just Wikipedia's sister projects. You can link to a page on MeatballWiki by typing [[MeatBall:PageName]], for example. See Interwiki map.
However, links to Wikipedias in other languages are done a little differently. You can link to these by typing, for example, [[:de:Hauptseite]] (replace "de" with language prefix). The colon at the beginning prevents the link from becoming an interlanguage link, which shows up in the left sidebar.
To hide the prefix from the link, use the pipe trick.
Bonus tip: the same basic syntax works in the search box. (Try typing in Meatball:)
