I am working on a project for school and I need to design and machine a cribbage board on a CNC mill. It was required to use pegs like normal cribbage, but being the normal risk taker and electronic geek that I am, I want to replace the pegs with LED's.
Project overview...
one LED per hole(120 holed per player)(3 players)(making 360 holes/LED's :o)
Each player has a couple push buttons that will control the board (move forward/back 1,5 clear... etc)
For me the easy part will be be the player controls and writing the code for them.
I am stumped by the best way to control the 360+ led's that the board will need.The current thought is to multiplex all of the LED's using a series of ATMEGA328's communicating with each-other through SPI. Is there a better way of doing this at a relatively low cost(<$100)?
If so, please share your ideas with me as the more brains at work makes projects more successful!
Thanks all! (If you have any questions, please ask!)

logic chips,
you can use multiplexers and NAND/NOR gates.
not sure how yet, but it can be done.

Use lots of shift registers.
HC595 is common
Or, use some matrix LED driver ICs
