Run Java 7u40 Embedded on Lego Mindstorms
Another excuse to buy Lego for yourself (only if you are a Java developer): Java 7u40 runs directly on the Mindstorms controller.
lejos provided the ability to run Java on the Mindstorms controller for many years now. Now the LeJOS community is working to run LeJOS on the new MINDSTORMS EV3.
Business idea: An autonomous "Seek and Destroy" robot who finds the CI "build breaker" :-).
