Daniel is right. Design of interfaces is an art, and usability is
a science, studied by professional designers. It isn't just "put
something fancy on the screen" without back thoughts. You have to
take into account psychology of human perception, at least.

Simplicity is often a winning approach over complex interfaces: say,
many MUD-s re-write the beloved SCORE output to heavy something-
don't-know-what-it-is. Primary priority of an informative command
is to give information in the easiest way for understanding by human,
it doesn't matter how many ASCII pictures and colours you put there.

Another horrible example is when most of game's items are painted
worse than a Christmas tree in decoration. Agreeing that it might
look pretty, it's absolutely not effective in way of quick analyse
of your screen. It can be formulated as general rule: anything which
is over-used loses its value.

Or: text for people, not people for text. :)
