Larrytheliquid has developed a unique presentation method called a "Gitorial" to demonstrate building a library in Clojure using Test-Driven Development (TDD). This innovative approach involves capturing the presentation within the Git revision control system, where each commit acts as a slide with messages explaining the changes. Viewers can explore differences between commits to understand modifications and can check out any revision to experiment with the code, supported by passing tests at each commit. This method allows users to create branches and test their ideas with the assurance of reliable tests. The Gitorial can be accessed at the provided GitHub link, as highlighted by Chris Wanstrath.
