I know Kung Fu! (or neo4j on Rails without jRuby)
summary
Shows how to use Neo4j with Rails (without JRuby) via the Neo4j REST API and Ruby wrappers like neography, architect and the homemade keymaker gem; demonstrates Cypher pattern queries (first- and fourth-degree traversals), a Matrix-style sample graph, and a real project sync where Postgres stays system-of-record while Neo4j answers degree-of-separation queries. Benchmarks claim 2 ms Neo4j lookup vs ~2000 ms in SQL on the same problem, Neo4j capacity notes (billions of nodes/relationships), and a working but fragile observer-based sync approach.
