There's been a lot of activity recently around a 10 day Star Wars minifig challenge on Flickr. eclipseGrafx has been participating and his most recent submission is fantastic. Take a look at this med droid and vignette. My eye immediately went to the droids' head leaving me to wonder, where did this part come from?
I then saw this companion pic of the figure in full. The head is actually a painted Buzz Lighyear part! The entire creation is perfectly proportioned from top to bottom
I also wanted to point out the lightsaber blades acting as a channel for the bacta fluids. Here's a use where the bubbles in the plastic make perfect sense!
