You may have noticed much in the press recently about “Prism” a spook lead programme for interrogating our electronic communications and then (?) sharing with other, like minded, States. But did you notice the Jerry Anderson/“Thunderbird” style logo? Horrid, I thought but…
At http://mirror-uk-rb1.gallery.hd.org/_c/natural-science/prism-and-refraction-of-light-into-rainbow-2-AJHD.jpg.html you will find the original image “FREE to download and use!
