For those of you that are visual and like working with rows and columns like me, I came up with this design:



You can have a lot more LEDs by using pins across ROWs and COLUMNs, but that adds more complexity than I can handle, and this is good enough for me.

By using a maximum of 8 pins per side in this configuration, you can use BYTEs and LOOPs to control lighting.
