other uses for bicycles

I spent the month of May on vacation in Northern Argentina, I didn't do much cycling, just a few days on a mountain bike riding around the city. What I did find interesting was this use of a bicycle. This peanut vendor pedals around a peanut roaster. He has a fire going to roast the nuts, and the wholw thing is shaped like a locomotive. He also has a water reservoir and a steam whistle.
