Here are a few links to some very cool shipping container homes. Shipping containers reduce a lot of work you need to do to build your home, but it's certainly not a "micro home" that can be moved. the 20' long units are closer to micro, but most are 40' and more than one stacked or assembled. It is an interesting idea on how to recycle these boxes.
Reality though is that getting one of these shipping container to your lot is very expensive. they will cost you upwards of $10,000-$15,000 per box to buy it and get it shipped to your building location and set on it's foundation. A lot of people are claiming far lower prices, but they are not including the price of delivery and the crane to lift it off the truck and set it in place. I have seen people build a standard home the same size for the same price as just buying the shipping container and having it delivered.
