Spice up your inbox with colors and themes

excerpts:

Gmail fans have been building unofficial extensions to spice up their
inboxes for a while, but up til now themes haven't been an integral
part of Gmail. We wanted to go beyond simple color customization, so
out of the 30 odd themes we're launching today, there's a shiny theme
with chrome styling, another one that turns your inbox into a retro
notepad, nature themes that change scenery over time, weather driven
themes that can rain on your mailbox, and fun characters to keep you in
good company. There's even an old school ascii theme (Terminal) which
was the result of a bet between two engineers -- it's not exactly
practical, but it's great for testing out your geek cred. We've also
done a minor facelift to Gmail's default look to make it crisper and
cleaner -- you might notice a few colors and pixels shifted around here
and there.
