I really like the Liquid Bioramba theme by yourmateian, but I missed a German translation. Also it's too multi-colored for my taste.
So I made a background with German text and de-colored the bars. You can combine it with the original Liquid Bioramba theme, so you can get a German colored version or an English non-colored one.
I also added an Aero-G background with German text and one without text.
Note: These are only replacement pictures, you need Liquid Bioramba:
