some sort of circuit substrate to build it, commonly PCB material or protoboard.

Wire to hook everything up, 18-22 gauge

resistors

maybe shift registers if you want to streamline the output.

Transistors if you need to invert your output pins.

Check out the bill of materials on several of the 'led matrix' instructables.

It's done exactly the same as single or bi-colour, just you have to triple the data lines for rows or columns. (thats when shift registers come in handy)

Two flat boards tied together and a person to walk back and forth with it.
