So how would I go about customizing the welcome screen? I know about initial-buffer-choice, but I’d like to customize the original one as a part of theme (I’m working on a Tron theme, and wanted to have all bits of it perfect!).
I don’t want to change the text, but I have an alternative design for the logo 🙂 It’s not really a replacement, and I’m not going to put a different logo instead, it’s just a minor remake to go with the color theme.
EDIT: below is what I’ve got so far 🙂
And the larger image:

EDIT
Sorry for making you wait. Here we go: https://code.google.com/p/tron-theme-emacs/ If you find a language mode where the theme misbehaves, I will try to fix it. I think I tried it once on a text terminal, rather than X-window Emacs, but I don’t remember how it was. So, that may be a problem. Also, some modes may come with their own faces. I tried to set some (like ECB), but these may not be complete / I’m not aware of all the possible faces. But, again, request for improvements are welcome.

To change splash image, set
