Looking for high quality and aesthetically pleasing cable hiding solutions

[AudioEngineer]

I'm looking for aesthetically pleasing cable hiding solutions for my new place. The standard white PVC square tubing solution is too ugly for my purposes. I need to run some cables along skirting boards, up one corner of a wall and then along a cornice and then along the ceiling to my ceiling-mounted projector. I live in Cape Town area, so suppliers in this vicinity would be preferred, but not required.
