I dont understand why you are using more than 30 wires to control 30 LEDs that are charlieplexed. You also dont mention how they are arranged, or any specific details that might help someone understand what you have going on.
You could add shift registers or LED drivers to reduce pinout, but you will still need wires to the LEDs, and no math will solve that.
If you have 30 leds in a 5 x 6 grid(multiplex), that would require 11 wires, since yours are charlieplexed, you would need less.
If the individual wires bother you, then maybe you could use a ribbon cable instead.
