Looking for "EXE"; a symbolic phenomenon which was seen in the sky, as stigmata like marks etc Any ideas?

I think it was called "EXE" but can't find anything on here, Google or YouTube which is strange because I remember finding resources and an official website the last time I looked it up. It was a crop-circle-like pattern that was photographed in the sky by a holiday-maker and also as stigmata-like marks on one individual's hands. Can't find a THING! Any help would be very much appreciated. x
