Instead of messenger's point of view, make it from the PAINT CAN's p.o.v.: we see similar obstacles, but it's all thru a slit in a box.
Concept: Take the Obstacles out of Painting A messenger guy zips through the city (on foot/bike). Camera view is from his perspective, so we never see him. He avoids obstacles like taxis, chasing dogs, old ladies. Gets to destination: an apartment & delivers cans of Benjamin Moore paint.
