It was a scratchbuilt board, perhaps 2' x 2', of a cobblestone town square. I think the fellow started off building it for his daughter but, after she lost interest in playing in it, he continued to build more around the square.
I think it was mostly blue/pink foam, with lots of bits made from Sculpy (polymer clay). He made mushroom people and other characters too. The buildings lacked right angles, flaring out towards the top.
It all looked truly fantastical. There were some of the most crooked telescopes I've ever seen coming out of the windows and the oddest angular chimneys on the most uneven of roofs, but he made it all merge beautifully.
I think one of the last buildings he did for the board was a tall observation tower of some sort. Stunning stuff. And the colors, though cartoonish, looked awesome.
Does it ring a bell with any of you? I used to have the link but lost it long ago. It was a blog, not a video.
