In the television show from a decade ago, the crew of Serenity, a Firefly class spaces ship used a cargo-mover called a Mule. On television is it was little more than a glorified 4-wheeler. But in the film Serenity, Malcom Reynolds and his crew get an upgrade in the form of a real life land-speeder. This beast of burden is a great example of scifi industrial design. I'm always curious about the details that get designed into these kinds of objects. Below is a series of labels/stickers that appear without explanation on the craft. At first they appear to be some kind of skull, but if you're familiar with the Firefly Universe, you will more likely recognize them as the octopus from the Blue Sun Corporation's Fruity Nutty Bars (they turn a man into a mouse) cradled in a Mule.
Regardless; Here's a little icon art for your enjoyment.
