What is a logic design project that I can do in two weeks or so during Xmas break?

I need to go to Ohio for christmas for family for about a week. Most of the time is spent doing nothing, though. Truth of the matter is that I haven't seen any of my relatives for more than once a year since i was about 8, so I have little if any connection with them. Thus I spend most of my time doing nothing. I don't have a car, don't know anyone up there, don't have a reliable internet connection, and don't like reading novels or solving supermarket puzzles. Well this year I wanted to be a bit more productive and actually get something done.

In my logic design class, we use a Xilinx Coolrunner II CPLD. I can get a 'design kit' from Xilinx for about $49 that has most of the stuff I need to program one.

The course itself is fairly extensive. The covered topics include:

[*]Combinational Logic, Karnaugh maps, multilevel realizations, cost efficient gate implementations, etc etc
[*]ROMs, PLAs, FPGAs, CPLDs, etc
[*]Sequential design, state assignment, state reductation, efficient state table assignments, etc.
[*]Three chapters on VHDL - one for combinational logic, a second for sequential logic, and a third for complete digital system design (which I haven't studied yet)

So I have a lot of experience, but all the 'examples' in the book can be done in about 6-7 hrs and aren't really all that 'interesting.' I was looking for a project that takes maybe 15-20 hrs and actually is somewhat 'oool', even if it is rather basic and not overly interesting.

What I would be getting

Does anyone have any interesting ideas that are doable?

you could step back a bit and design a Motorola HC6805 in VHDL or Verilog, I did this in around one semester, but you can just desing one or two parts of this.

Damn, I guess designing a few parts of it wouldn't be too bad. The two chapters left in my book are 'circuits for arithmatic operations' and 'complete digital system design.' Maybe after the next chapter I'll have a better picture into how part of the Motorola works.

Do you have any referencing documentation somewhere to help with it?

Or design an audio processor in vhdl/verilog.. something like an equalizer or a low/high pass filter. you will need an adc/dac of course.
