grown, printed, or programmed, artifacts in steelpunk are built (typically with rivets). Examples include films like Snowpiercer (2013), as well as those in the Mad Max, Terminator, and Robocop film franchises; stories centered on comic book characters Barb Wire, Iron Man, and Stainless Steel Rat; and Heinlein juveniles novels. Cassette futurism/Formicapunk Cassette futurism is a subgenre of cyberpunk that reimagines early 1980s aesthetics as popularized by the IBM Personal Computer and imitators, regardless of the real time setting of the media. Notable elements of cassette futurism includes loud, bright, contrasting colors and geometric shapes, a tendency towards stark plainness, a lack of powerful computers and cell phones, and the prominent usage of 1980s or 1980s-inspired technologies such as: magnetic tape data storage, cathode-ray tube displays, computer systems reminiscent of microcomputers like the Commodore 64, freestanding music centres, small, monochromatic LCDs as opposed to full-color screens, floppy disks, and analog technologies. The internet, or some analogue to it, may exist in a cassette futurism work, but be used less frequently in data exchange than physical media. Notable cassette futurism works include the designs of Syd Mead and Ron Cobb, the 2018 Netflix miniseries Maniac, works featuring Max Headroom, Blake's 7, the 1995 film Strange Days, and some elements of the TVA in the Disney+ series Loki. Rococopunk Rococopunk is a whimsical aesthetic derivative of cyberpunk that thrusts punk attitude into the Rococo period, also known as the late Baroque period, of the 18th century. Although it is a fairly recent derivative, it is a style that is visually similar to the New Romantic movement of the 1980s (particularly to such groups as Adam and the Ants). As one steampunk scholar put it, "Imagine a world where the Rococo period never ended, and it had a lovechild with Sid Vicious." Rococopunk has most recently been seen through the artist Prince Poppycock as featured on The X Factor. Fashion designer Vivienne Westwood, often known as "the Queen of Punk Fashion," also mixes Rococo with punk stylings. Stonepunk Stonepunk refers to works set roughly during the Stone Age in which the characters utilize Neolithic Revolution–era technology constructed from materials more-or-less consistent with the time period, but possessing anachronistic complexity and function. The Flintstones franchise, including its various spinoffs, falls under this category. Other examples include the episode "The Nightmare of Milky Joe" in The Mighty Boosh, Gilligan's Island, The Croods franchise, and Castaway (2000).
