Apologies if anyone has seen this before.
There is a fine line between enthusiasm and insanity. While this isn't quite building Devil's tower out of mashed potato, I'm not quite sure which side of the line it is on. Use the little men for scale.....
By the looks of it it is only 2/3 complete length ways, with the bow section to be added. And before you ask, the aircraft are as accurate as the medium allows.
Very impressed, and somewhat unnerved at the same time.
And if you don't get the mashed potato reference, you need to see more movies, specifically 70's ones about alien contact.
