Comment 1 for bug 403828

From your description, It seems this is not a bug you are filing but rather a misunderstanding of why the light source is where it is.

If your description matches one of the following images at the following link:
https://wiki.ubuntu.com/Artwork/Incoming/Karmic/Boot/Demo#Splash screen

Then this bug should be closed as this is the intention of the artists.

You may leave feedback at the bottom of the page where it would be more appropriate.

Hope this cleared the issue.
