Rgb Led strip multiplexing

Ok I'm wishing to cover a 1.5m by 1.8m wall in my house with rgb led light strips so it can be used as a display or a vu display. I roughly calculated that I would need about 10200 LEDs to cover that space nicely and I'm just wondering is it possible to multiplex rgb led strip lights and also is it possible to multiplex that amount of LEDs

Do you want to multiplex STRIP or EACH LED...?
Do you want to give effects? what power supply you have with,,?

Disregard the original question
Basically I'm trying to make a audio visualiser out of Rgb led strips but on a very large scale.
If you where to do this how would you go about it and a simple but effective way that makes you go "wow that is cool". Thanks in advance.

Have you seen the "Wall of light" here:-
