This stars background I find in the internet.
A logo blending together the symbols of the world’s three great monotheistic religions has journeyed from being a work of museum art to a protest slogan to an affirming celebration of faith.
From what I can gather the CoeXisT symbol was created by the Polish artist Piotr Mlodozeniec for the Museum of the Seam in Jerusalem. The museum sponsors the Coexistence outdoor exhibition which features exhibits by 42 artists and since 2001 has been winding its way through many of the world's most volatile cities.
I did a remake in Inkscape and Gimp of this logo.
The background is Free from www.crestock.com, with other beautiful wallpapers there.
