Recently moved to a new appartment and took the opportunity to prepare my bedroom for an indirect lighting solution. I'd like to install about nine meters worth of hue lightstrips around the ceiling of the room - ideally as two or three separate lights. There's one outlet (just the raw wires, really) available in one of the corners of the room, about ten centimeters below the ceiling.

Has anyone done something similar and if so, what did you use / how did you do it? Anything to watch out for? I've already accepted that I'm likely going to have an external power-supply. How to power the controllers, though? I'd like the installation to be as clean as possible.
