A simple poem I made in 20 seconds on how skipping quality for your intro graphic can screw up an entire web-page:

Realm of Heck

Make it level, make it square
You'll never know how long it's there
Thing of beauty shaped so rare
Ever after left so bare

Dotted pixel, point of light
Blazing through your work of might
Ever-after marring right
To perfection, lost to light
