8 MAX72XX is the limit

I reached the limit on how many MAX7219's can be chained together. That's 8. Good article here, so I'll have to use another 3 outputs on the arduino for my 5th matrix. Photos soon.

Today, I was able to hook-up an 8x8 R/G led matrix and display X,O and G in red. Still need to get Green going and then re-write the code in Flash so I can connect it to the internet.
