Here's a sweet chord progression I just found:

The root chords aren't anything too fancy: just I -> VII -> VI. But the voicings are pretty neat:

Left: A E G, Right: B C E G
Left: G D F#, Right: A B D F#
Left: F C D, Right: G A C E

The second chord is just the first transposed down a whole tone, but the third chord replaces the 7th in the left hand with a 6th.

(And hey -- it does just say probably something about programming.)
