Barely, but the exposure that I got, I found interesting. I was listening to an audiobook of short summaries of 50 spiritual classics (or maybe self-help)....the summaries are fun to get a lot of background quickly without investing too much time, and also to find ideas for what books would be worth taking the time to read. One book summarizing was Ken Wilbur's "Theory of Everything." It had a brief explanation of the concept.
If you do a Google image search on "Spiral Dynamics," there are a bunch of cool illustrations explaining the concept -- more interesting than reading text describing it.
