Today, LEGO has announce a new Android App for LEGO MINDSTORMS NXT. If you have an Android based phone, you can use this to manipulate your LEGO robots using Bluetooth. I have a Motorola Droid, and I have two MINDSTORMS NXT sets, but have never built anything with them. I really should get around to doing something about that.
