It's a great list and by now a fairly standard list. You can find variations and extension of this in many places. I recall one of Feynman's standards tricks was seeing if he could get a desired result without going through the expected stepped. I think Douglas Hofstadter's analogy project was aim to construct an AI using this (an approach that hasn't gotten the attention (or research grants) it deserves imo).
