The author of the text created a screencast that demonstrates how to set up a Neo4j instance via Heroku and connect to it from within a Google Spreadsheet using appscript. The process involves registering at Heroku, installing the heroku gem, creating and installing a Heroku app, adding a Neo4j addon instance, uploading existing Twitter data to the graph, creating a custom Ruby app, executing Cypher queries, connecting to the app using a Google Spreadsheet, and building a small bar chart from a Cypher query. The author notes that while the screencast is not perfect, it is an acceptable first attempt and encourages viewers to suggest topics for future screencasts or create their own screencasts about Neo4j topics.
