There are a couple different interactive resources available on ni.com to learn more about Lookout.
1) First, there is a Getting Started Video for Lookout 6 which provides a short introduction to the environment and development concepts. It is found at the following link (the Lookout homepage), by clicking on the "Product Demonstrations" link on the right side of the page:

2) Also, there is a twelve step tutorial that leads you through the creation of an entire process with Lookout. This tutorial focuses on three key concepts: configuring a process, a network connection, and a web client. It may be found at the following link:
