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. |
