The design would be easy. The problem is scale, 12"x12"x1", w/beveled edges, and the shear number of tiles you would need.
An entire office? That would be expense. Print cost would probably be $50 to $75 per tile, at 12"x12"x1" each. Most printers aren’t even capable of printing something that big, 6"x6", or 8"x8" is typical. Did you want to print them yourself?
You could use 2" thick insulation foam board, and paint it. Cutting individual tiles would be easy, but may not fit seamlessly together. Curving the pattern in to full 4ftx8ft sheets could be done, but there would still be a seam where the panels butt together.
