Been meaning to post this one literally for years... It's always when I'm watching one of the films and then I forget. :)

The design cues are also in different scenes in the original Star Wars films. I always wondered if the designer picked up some of his design styles from the films.
Update: a few more design cues from the original films added below. Oh, and ignore the Oreos, although, the size of an Oreo is roughly the size of one of the knobs on the particular synth I thought of. :)
