Well  how do they work ... :)  I think a simple cpu design that is 
flowcharted with multi-colored leds
( say red for 1's green for 0's )  where the data walks from gate to 
gate in the alu.
 Say 32 words of memory for program memory ( loaded from rom ), and 16 
words of ram,
 and few hands on I/O devices for the people using the project.
