Amazing GRACE

Amazing GRACE and GOZE and breath taking results:

Notice that the deep red areas are more or less -very roughly- antipode. That reminds me of another World map in relation to sea levels:

With a little imagination you could draw an oblique geographic world from that, the poles being in the centre of the blue spots, the equator following the big orange wave. Aint it curious?

That second link is very interesting. Actually I just remember now.. a few weeks ago there was a very stormy western wind. I was at the west of the IJsselmeer (a lake) and the water level was SO low! that you could actually go down and walk on the bottom of the lake for a considerable length from the bank.. reminded me of that tale where the water parted and Jesus walked across a lake.. sounds very possible in such a scenario
