Cornell University has been using DE2/DE1 for 9 years in course teaching and collected all their students projects to share in their webpage:
http://people.ece.cornell.edu/land/courses/ece5760/finalprojects/ More than hundreds of complex projects were implemented on DE2/DE1 boards; all the source code with complete reports were also shared on the web. I learned a lot from their website and even built our company products using the code/skills learned from the Cornell Website.
The professor, Bruce Land, also posted his 30 lectures on youtube:
