The other Watchmen technology that I have trouble accepting is Rorschach’s mask. It’s made from what he describes as a “new Dr. Manhattan spin-off fabric. Viscous fluids between two layers latex, heat and pressure sensitive [ . . . ] Black and white moving. Changing shape . . . but not mixing. No gray.” Rorschach also relates that he learned how to cut the fabric using heated implements to reseal the latex.
All of this is quite plausible to me except for two things:
- A “fabric” such as Rorschach describes is achievable without any new Dr. Manhattan technologies. I’m not sure latex will work, but two layers of plastic (one white, one transparent) will do the job just fine. And having the black and white fluids move without mixing is simple; just use liquids that aren’t miscible. (For an example, see the nearest Lava Lamp, or any of those oil-and-water desk toys like this one.) But you don’t want to wear a mask made of that stuff over your face, because you won’t be able to breathe or see.
- Viscous liquids between two layers of “latex” can produce moving patterns of black and white, but will those patterns be laterally symmetrical? The ones on Rorschach’s mask are, without exception.
Rorschach’s mask is simply impossible to make with 1980s technology, and his reference to Dr. Manhattan doesn’t really explain how it could possibly work. However, it occurs to me that we are now just a few years away from being able to make it with 21st century technology.
The key is e-paper of the sort used in the Amazon Kindle. Right now, that technology is under glass (or plastic, more likely), but one of the goals of that industry is to create flexible displays that can be rolled up or folded, like a sheet of paper with e-ink instead of actual pigment. Initially, this will probably be something like a shower curtain, but eventually it may be possible to map an e-ink display onto a fabric porous enough that you can actually breathe and see through it.
You’ll need a microprocessor to manage the patterns being displayed — that’s how you keep them symmetrical. The processor is embedded in the collar of the mask, along with a small battery and a simple switch for turning the inkblot animation on and off. No fluids are required, and no help from Dr. Manhattan, either. I expect to see it at science fiction conventions by 2020.
