Now I know it's an art project and all, and it may produce some neat stuff. But it's a ridiculously upper middle class conceit that walking in Los Angeles is special. It's not special, it's just painful.
I spent ten years in Los Angeles without a car, riding the buses and burning a lot of shoe leather. While I did learn many things, see sights, get a sense of the city at ground level etc. etc., mostly I just was dirty and tired mostly, late for everything, and often worried for my safety.
Lots of people walk all the time in Los Angeles. We call those people "people without bus money who need to get somewhere".
But I bet this project does produce some interesting images.
