---12--12--10--10--8-8----------------------------
-----12--12--10--10-8-8---------------------------

sounds cool when repeated a few times, or when another note is added at the end like this:

----------------------------------------------------
----------------------------------------------------
-----------------------------------------------------
-------12-------10-------8---------------------------
---12---12---10---10---8--8---------------------------
-----12---12---10---10--8--8--------------------------

also, when done like the following, it sounds like an AFI song..

---12-12-12-12--10-10-10-10--8-8-8-8-----------------
---12-12-12-12--10-10-10-10--8-8-8-8-----------------

if you experiment with it, and put it all together in some arrangement it sounds pretty cool.
