Mainly because:
I want a lawn my pets can safely munch own.
I want to attract more hummingbirds, butterflies, and bees.
I want to look at the pretty flowers.
I don't want to water.
I don't want to mow.

I think I'm going to mix the three seeds, spread them in the yard (mostly dirt, now) and see what happens.

Any thoughts?

I want mine to look a little more "wild".

I was thinking the same thing too. I will "borrow" the idea and form some patterns in my garden with herbs, but probably not as formal as shown in the pictures.

First try: Tilled and raked the area with a tractor, as one would do for a grass lawn. Broadcast the seeds in the spring, as soon as I thought the soil would be warm enough for the seeds to germinate. This was pretty much a disaster. For one thing, I didn't see any seedlings, I suspect because herb seedlings aren't robust enough to root in a firm lawn-like seedbed. For another thing, the necessary watering encouraged crabgrass, which quickly covered the ground. I also had problems getting some parts to stay moist, maybe because the water ran through too quickly.

Second try: I addressed the moisture issue by spreading and tilling in 16 yards of compost. After tilling, I didn't rake, rather left it loose, and walked on it as little as possible. This time I seeded in the fall. Got some pretty good germination, but there were a couple of problems: 1) Had to reseed one part, after I wasn't vigilant enough about not letting it dry out; 2) It was hard to water evenly, and some parts got too wet, which ruined the seeds there.

That was last fall. Now the area is carpeted with winter weeds, some of which I've pulled out (big area to pull weeds out of). But there are some signs of the herbs starting to poke out of the ground. It's been unseasonably cool so far this spring. I'm hoping that when it gets warm, the winter weeds will have had their day, and the herbs will take off. I don't think the herbs will do very well without water, so I expect to water them in the spring and summer. I also did plenty of watering last fall. I have a well and don't pay for water.

Herb seeds are small, and you have to mix them with a medium in order to spread them. I used sand as the medium for the smaller seeds, and cat litter for larger seeds. I bought seeds in bulk (which can mean 1 oz. for herb seeds), in amounts that would yield me roughly 10 seeds per square foot (i.e. 30000 seeds for the 3000 sq. ft), since I knew there'd be a lot of loss.

Anyway, it's a challenging project, but you could end up with something different from everyone else on the block.

BTW, if it doesn't work out this year, and I have to try again, I'm thinking of planting a "nurse grass" along with the seeds, in the fall, to keep the weeds under control while the herbs are getting established.
