Nowadays, it is virtually possible to do just about anything with your Android smartphone. Apart from unlocking your car and opening your garage, you can also make payments without any cash. All you need is your Android smartphone and you’re good for anything.

A new development in Android smartphones just proved this fact.

A French developer placed an RGB lamp inside a typical McDonald’s cup. Using a Wildfire S, he was able to change the colors of the lamp.

“The orientation of the phone is detected by the built-in compass (magnetic field sensor 3-axis) parameters hue, saturation and brightness are converted to RGB and then sent via a TCP connection to the Fox board that controls the lamp,” said the developer.

On the video, the lamp is able to change colors when the developer dragged his fingers along the screen and while he turned his phone around. Even though it’s not as functional as the other tasks you can do with your smartphone, it’s still pretty cool. But we do wonder whatever happened to Android @ Home, which was first announced at Google I/O 2011.

As for the lamp, I want one! It would be pretty cool to have this during a party in your own home, right? What do you think?
