Just in case you were planning to start playing with your Sense HAT, it appears a new version of the Python library was released.
The main change of note is new the joystick functionality. Previously you would've had to use libraries like pygame and evedev to capture input events, now the Sense HAT library supports the joystick directly with no other dependencies.
The library will be part of the next Raspbian release, but can already be installed manually.

Have fun!
