Ninja Blocks started out as a Kickstarter project with the intention of connecting your physical world with the World Wide Web (WWW). The Kickstarter funding smashed its initial crowd-sourcing goals, and has since then shipped thousands of Ninja Blocks devices.
The platform is controlled by simple if this, then that style tasks using effectors and actuators. Both effectors and actuators can be made up in the physical or virtual world, which means you can do things such as post on Twitter when a door sensor is triggered by an opening door or turn on a lava lamp when a file is uploaded to Dropbox.
