You can read a little more about BlockyTalky here, on their development site. The project brings the Raspberry Pi, BrickPi together using their graphical programming language. A screenshot to the right shows the language is turning out to look a lot like Scratch, but web-based.
You can watch their full demonstration video above. They have a beautiful line-follower that runs incredibly smoothly, and finally a remote controlled robot that they control with the gyroscope of a cell phone or laptop.
