This claim is trivial to debunk in a 3D program. Here are 40 blocks in a straight line on a flat surface, "photographed" with 75-, 500-, and 15-mm lenses respectively. (But I guess Blender could be a conspiracy.)
he would have to add a lego texture to the blocks. or we wouldnt see any disappearing feet like we do in the Dubay vid.
yes the grey blocks at the end would be a tad bit shorter, but im not sure that would be visible enough to viewers.
Curved surface (a white heavy cardboard top on a somewhat smaller box on a table, that I use as a standing jigsaw puzzle table. It sags a bit where it extends beyond the box).
Image one: Lego on the board, equal distance apart. Note that their shadows are not visible for the last couple.
Image two is from board height, showing the curvature.
Note that some knobs are hidden for for the last three.
