The Neo4j community team devised an event with hacking challenges that included recording interaction-graphs based on OpenBeacon-RFID tracking and creating visualizations in a Zen Garden style. Andreas and Michael discovered the Zen-Table project, which is an autonomous Zen garden in a box that can draw static images or dynamic renderings via USB. The team arranged for the first Zen-Desktop table to be shipped and gave it to their Heroku friends as a token of friendship. At GraphConnect, they will have a desktop Zen-Table waiting with a challenge for attendees to come up with graph renderings suitable for visualization on the sand of the Zen-Table, allowing external access via HTTP.
