Installed moonlight on Ubuntu from source by following these instructions (there are some typo's but they are understandable and correctable).
All in all, even being still under heavy development, what Miguel de Icaza has achieved (with moonlight, just like with mono) is amazing.
After I posted the above picture on Flickr, John Montgomery was amazed to see PopFly (his creature) working on moonlight, and he linked to me from his blog.
