The world's biggest QR code is a 22.05 meter square, not counting the white border, which is partly cut by reentrant corners, one of which has a tree in it.
"The finished product will cover most of the 10,000 square feet of space. It’ll be so big each of the pixels will be at least one square meter." http://www.wcnc.com/news/business/Worlds-largest-QR-code-created-in-Charlotte-131013048.html The actual size of a module ("pixel" in QR code terminology is something of which there are at least sixteen, all the same color, in a module) is 1.05 m × 1.05 m. The code is 21 modules by 21 modules, plus a 4-module border. Thus the areas are 486.2 m² excluding the border and 927.2 m² including it. On June 24, I brought my 50 m tape to the building and went up with some others in a forklift to the roof. It was not safe for me to get on the roof, though, so I handed the tape to someone else. Afterward, the guys who went up there drew a sketch, and I took the sketch and drew plans. The day they went to mark the grid on the roof, I was sick and could not walk. The following exchange took place on IRC: [15:41] <_ski_> Thanks, phma for doing the drawing. It was very helpful today. [15:42] <phma> welcs [15:42] <_ski_> Even though I had tol conver m to ft [15:42] <_ski_> ;) [15:42] <_ski_> We only had the "100 FOOT" tape. [15:43] <phma> and I have only one working foot [15:43] <phma> but 1.5 meters Pierre -- When a barnacle settles down, its brain disintegrates. Já não percebe nada, já não percebe nada.
