cuneiform script on Wikipedia, now you can. Technically there is not that much to it.
This is what it took to get the text you see on the infobox of the cuneiform article.
This is fun, nice but not all there is to it. What is really exciting is that you can now write in many, many scripts and expect that the person will see the text properly.
It is no longer necessary to create a screenshot. If anything, this is the time to find all those screenshots and replace them with the proper text and invoke the ULS and its webfonts.
