The Great Ubuntu Wave (Japanese text)
Created using Gimp by: NeverSage
I originally made this only to use personally, but since I can't program I decided to share it with the community to try to give a little bit back.
This has only been tested for Karmic Ubuntu Netbook Remix which uses xsplash. I doubt the formatting will work correctly if your settings are anything other than those defaults. You may need to manually rescale the images to properly fit your settings. If I have enough requests I will submit an update with more sizes.
Unzip the archive. Go to /usr/share/images/xsplash and backup the identically named files there. Copy the unzipped files to that folder.
throbber_small.png is just a copy of Ubuntu's default. It is included just in case.
The Japanese text reads "ubuntu".
The background is "The Great Wave" by Hokusai.
