Yes, definitely. Customer supplied some code that I had to incorporate into a new JEE app (actually J2EE back then). I liked that code because it was just way cleverer than anything I ever expected to find in an enterprise Java app. It implemented a trie to return a list of partial recordings to make a full sentence (which was the input). It was space and time efficient, but also extremely clear, logical, and easy to incorporate into our code base. And best of all I was able to use those ideas to solve a similar problem in the next project.
