  If I look closely at the Roman ones, the outlines are done with square tile following the lines. The infill also follows the lines, with partial ones to fill in places where the square is too big. The partial ones are simple straight cuts, today you can get a snipping tool to do that. Not necessary to chisel them. The joints are hardly precision cut, in fact, the unevenness is part of the charm. Don't need to do the whole floor, just a section, like a "medallion" that is done in wood floors. Medallions in wood are a lot more skilled to make, because you can't fill the gaps with mortar like is done on the mosaics. I can't see more than an afternoon for, say, a 3x3 one.
