- Please consider users with lower screen resolutions when designing this. Try to make a layout that can be made 'liquid'
- Also consider international users when laying out the position of text on the screen - designs that allow text plenty of space to shrink and grow are preferred.
- Also! Consider widescreen monitor users.
Hints & Tricks

(write-up by Andy Shellam)
The RHGB screens are simply PNG images in the /usr/share/rhgb folder, and can be replaced by custom ones.
- To create a custom "throbber" (the animation of a few circles spinning round), create a PNG image of 288x24 - then in that image you need 12 images of 24x24 placed side-by-side, so when viewed left to right - that's your animation. Replace the /usr/share/rhgb/throbber-anim.png image with your image, reboot and you're sorted!
- In Fedora, the /usr/share/rhgb/large-computer.png isn't used - there are 2 other images - one which is the fedora system logo (the bubbly f), the other is the word "fedora" in the bottom-right corner. Replace these with your own PNGs and bingo, you've got a nice customised system :)

GNOME Splash Screen
Metacity (Window manager)
The main visual component of metacity themes is the titlebar of windows, but there are other things you can do with it too.
GTK (Gimp Tool Kit)
This refers to the basic look of windows... their color, the appearance of their widgets, etc.
The widget factory is a great program for testing the look of your themes. The Widget Factory link below also has a great screenshot of the program, displaying all of the different widgets that can be styled for GTK2.
