` :::Thank you. As a matter of fact user:Invertzoo and me were the ones who completely re-wrote the article. From many images that are used in the article I believe this one is one of the most interesting. I saw this kind of display only two times, two days in a row. I was surprised to find out that This effect was first described in the medieval King's Mirror like this ``hafgerdingar look as if all the storm-waves of the sea were gathered together in three continuous combers; the three wavecrests surround the whole sea in such a way that there is no escape (opening) ; they are higher than big mountains and as steep as precipices, so that in but few cases have people escaped from the sea when this has occurred.`` It is amazing that medieval explorers saw and described it. I assume it looked really scary to them. :::I have Flickr account, but I forgot, when I used it the last time.  :::Best wishes.  `
