Well recently I was using Ubuntu KDE, i.e. Kubuntu. You can customize it to look and feel pretty much like anything you want!
For example, are you tired of the Ubuntu logo rotating as your computer boots? You can change that. Are you tired of the boring login screen when you type your password? You can change that with two programs I helped write. Here they are.
ISS-Sunrise shows the sun rising over Earth while your computer is booting. You canand follow the instructions in the readme file.
PenguinOfLiberty is an alternative login screen with animation and sound. You can. Again follow the included instructions. They come as zip files. Unzip them by clicking on them. Ubuntu will give you an option to extract the files. Extract them all.
I like PenguinOfLiberty. It shows a statue of Liberty that looks like a Linux Penguin at night. There are little stars floating about and sounds from the city and the ocean sounds you might hear in New York. I spent a lot of time developing the sound track. It annoys my wife whenever I reboot my computer, though!
Here’s a screen shot of the login screen on my computer.
