Scrolling e-paper display   (+1, -1)  [vote for, against]
smoothly scrolling single-line display

For my e-book hat

A flat belt of epaper material stretched between two rollers. On the backside (non-visible side) there is a print head that impresses the ephemeral image onto the epaper belt as it passes by. The rollers scroll the belt along smoothly at a variable speed.

Avoids the choppy headache-inducing look of simulated scrolling on a pixellated display.

a goofy annotation about just duct taping a thermal printer running on a band of liquid crystal paper to a persons head yet the removability of the hat part is nifty

OK, here's an idea to implement this concept. Two liquids that do not mix: one white, one black. A screen of extruded clear plastic like coroplast but with finer channels. Each channel is fed by a valve that will admit either black or white liquid. At the 'exhaust' side, a separator divides the liquids into their respective reservoirs, to be pumped back around the circuit.
