Interact Labs was involved with the 2nd Minecraft in Leicester event this weekend. Our goal was to demonstrate how Minecraft can interact with the "real world" in various ways. We did this by showing how you can 3D print Minecraft objects and how you can use the Raspberry Pi (and by extension its GPIO port) to control Minecraft running on the Pi. We also had a robot arm to show the sorts of things you could control with a GPIO-connected Minecraft world. This is a work in progress, but we hope to be able to demonstrate a direct connection between Minecraft on the Pi and the robot arm soon. There are pictures from the event here on Flickr and a video interview with Sean Clark about the even here on YouTube. If you are interested in Minecraft on the Raspberry Pi feel free to come along to the Digital Makers Group on the first Saturday of the month - it's certainly something that the group would be interested in developing further.
