This is a Usplash theme created from the Debian Tango wallpaper here:

I deserve no credit at all for the image; I simply compiled a Usplash theme from it.

Just to answer the questions which are sure to come, I used the Xubuntu Usplash source to create this, so you may want to rename the usplash-theme-xubuntu.so to something easier to identify, like debian-tango-usplash.so, or something like that. I made sure the progress bar worked for my screen and resolution, but you may have to adjust some of the settings for your own configuration, which is why I included my source files. I couldn't figure out how to take a screenshot of it, so just imagine the wallpaper with a progress bar at the bottom. I followed the tutorial linked below, in case you have any question as to my methods. I'm a total n00b at creating these themes, so I'm sorry in advance if it's incorrectly compiled or whatever. Good luck!
