Thanks for sharing this with us all. I'm looking forward to making this with my son as his first micro project.
As we have heaps of them, we will be using LED's instead of LED matrix's, I'm trying to work out the polarity of the ones used in your schematic, do the Y's represent the Anodes or Cathodes of the LED's please?

The devices I was using were common cathode types. 16-bits of row (Y) data are shifted in and then the appropriate column (X) is enabled. With that said, it is extremely easy to use either common anode/cathode devices - just a couple of minor edits.
