Fun stuff here. Actually the ray guns put me in mind of the look and feel of the weapons you might find in post-plague Chasm City (Revelation Space series by Alastair Reynolds)
The blurb from slashdot
""Wired is presenting a gallery of artwork that inspired Weta's collectible rayguns, plus exclusive photos of the retrofurist sidearms. The article offers more than just images; each weapon has a description of where they were inspired from, as well as possible uses. 'In this illustration by Greg Broadmore, a hunter poses with his latest kill and his elegant retrofurist rifle ... "I started drawing these things just for fun," says Broadmore. "I did dozens of designs, all really stylized and Flash Gordon looking. I remember those black and white serials playing on TV as a kid and the imagery always stuck with me. Really hokey, but really scary and weird at the same time. And, of course, if you're a fan of classic rayguns you'll see the influence of the old toy rayguns. The Buck Rogers disintegrator pistol -- of course directly referenced in Han Solo's blaster in Star Wars -- is iconic, and that original raygun, along with many others, inspired me massively.'""
