Omaha has a big art project called the J-Doe Project we've been doing for a couple years now - invite local artists to create 6ft tall fiberglass J-Doe statues and then put them all over town in all the public spots...dumb if you ask me, but it seems to be popular. Some of the J-Does are actually pretty creative.
To me, it's grafitti. To others, its art. Read about it or see most of the Does at
