X-IVi is a obvious name for two reasons: 1. The base-theme was "Ivi" (Thank to "nale12"). 2. X-IV means 10.4 (Lucid) and the simple "i" means Design (iPod, iMac, ...), but don't care really about the "i".
Okay now about the theme: So I wasn't really happy with "Finestly Yin-Yang" for some limitations I had.. (only the murrine-engine). I took the decision to mix it with some pixmaps for get a higher level. With Ivi I got the right base for begin it again. The idea was to create a real Human-Theme (brown-tones and almost rounded). But this one had to be nicer than all I saw before and smooth (low contrast) for match better with the new Humanity-Icons. I am not a "code-hacker" and more a graphical-artist. But don't worry, I put all my best in it and I thinging it's work very well.
