I have an LED matrix that, strangely, has 2 sets of 12 pins on opposite sides, so 24 pins total. How would I go about hooking this up?

This is very probably a 8x8 bi-color LED matrix. It's got 8 rows, 8 columns of red LEDs and 8 columns of green LEDs, hence the 24 pins.
So probably something like this
