I have a job that lets me be this way. The development style is rapid application development. We spend 6-9 months on a certain module for a larger software suite, and once it is released we may enhance it, but usually we move on to building the next module. Its all part of the same overarching project but the needs of each specific module differ significantly. The places you will find this kind of project are in emerging markets. The market doesn't know what it wants yet and you can help shape it.
