We went over to our local source for pavers and ran the numbers against the colors they have... turns out, the only pavers they have in truly distinct enough colors are 4x8 (nontumbled). To use those I'd have to use two bricks for each pixel, making each pixel 8" by 8". Sadly, that would make Mario 8' wide and 10'8" tall. That's too big, it would dominate the front of our house.
My wife and I agreed that using pixels in the 4" range would be best. That would give us a Mario 5'4" tall and 4' wide. I haven't been able to source any 4" square pavers, though. The local source had 6" pavers in less impressive color selection than the 4x8 stones, which would produce a lightly colored Mario of 8' tall and 6' wide. Bigger than I want, not as much color as I'd like, so don't want to go that way.
The only way I've come up with so far would be making 4" blocks by cutting the 4x8 blocks in half. That would give us good colors and 4" blocks. Inconsistent edges on the cut sides would be a potential drawback and I do not want to cut 96 bricks in half (best case) at a minimum without being sure the results will be what we're looking for.
So, for now, the search continues for the right materials.
EDIT: Ed, that vendor has some really good potential 6" stones... but all of their locations are in FL.
