For those curious about the new Daily Grail icon (designed by yours truly), here's a brief explanation of the design.
It's basically a shield knot (used for protection and warding), in a Celtic style, based on circular geometry.
It invokes the gods of the four corners of the earth and represents the four elements, interrelated and united in the fifth. There's also a Brigit's Cross and swastika visible within the circle.
On another level, it combines the shape of a chalice with a hint of the letters D and G.
Hope you like it - and thanks to the Daily Grail for the inspiration!
