Website Background
This background .svg is inspired by
Bridget Riley (born 1931 in London) where she painted in 1967 her first stripe painting.
My website background is made by this code:
c1:=RGBColor[({0,155,175}+RandomInteger[{-20,20},3])/255]
c2:=RGBColor[({238,60,46}+RandomInteger[{-20,20},3])/255]
color:={c1,c2,None,c2,c1,None}
fil=MapIndexed[#[[1]]->{{#[[2]]},color[[Mod[First@#2,6,1]]]}&,Partition[Range[51],2,1]];
style=Flatten[Append[#,#[[2]]]&/@Partition[DeleteCases[fil[[All,2,2]],None],2]];
g=Plot[Evaluate@Join[Table[1/5 (1+n-Cos[(n Pi)/5+(2 Pi x)/3]),{n,14,-3,-1}],Table[1/5 (-5-n-Cos[(n Pi)/5+(2 Pi x)/3]),{n,-2,30}]],{x,0,10},Filling->fil,AspectRatio->Automatic,PlotStyle->style,Axes->False,PlotRange->{{-0.2,10.21},{-7.41,3.4}},ImagePadding->0.1]
Export["panel_1.pdf",Graphics[Inset[g,Automatic,Automatic,Scaled[1]]]];
