This city is weird.
For one thing, there aren't that many houses. There are some, but they're rare and mixed in with all the non-houses - big community-garden-type things attached to no specific dwelling, shops, parks, food carts, amphitheaters, workplaces where people are manufacturing clothes and suchlike, storage-unit type complexes. The lack of houses doesn't seem to have a relationship to the number of people out and about. It looks like everyone aged ten and up in this entire city is out and about - the only people who've stayed home, apparently, are the smaller children, of whom the visitor can observe literally none. Everything's brilliantly colored, often without obvious paint application, like they happen to be able to find pink wood and green stone that also has suitable structural properties, but the parks have normal green foliage and brown tree-trunks. There are cart-like businesses that resemble the ones selling street food except they have mice, live mice, that people are paying to hold for two seconds and then give back. A number of people have pets - dogs, cats, foxes, birds, a gerbil with wings.
There are four suns in the sky. They are different sizes and colors - the biggest one is white, the smallest blue, the middle two yellow-green and deep red. It makes the shadows kind of weird.
There is no evidence of electricity.
The library is a big blue stone building. It looks like half library, half public lounge, like it not only encourages but expects lots of people to spend all day hanging out in one of the provided chairs reading books. Some of the seating is outside, with awnings that would probably also work on rain keeping the sunshine off.
