Good luck.

The LCD you're looking for is an ultracompact COG (chip on glass) type
graphic LCD.  These are used in cell phones and other small devices.
 They can be had for under $25 each from

A little larger than a quarter.  The COG means the controller is on the
glass itself, so you don't have the bulk of another pcboard.

I'd recommend as small a PIC as possible.  The controller has both
serial and parallel modes, and an onboard voltage booster (which, I
believe, means you don't have to supply the normal -8v for the LCD
driver) and runs from 3-5 volts.

You should be able to use as little as an 8 pin pic, a few capacitors,
and a 3v lithium watch battery to run this thing.

Be aware that while this isn't a terribly difficult project, it isn't a
beginner's project either.  Be prepared to spend a lot of time learning
how to program the PIC, especially for timing, and another big chunk of
time for LCD interfacing.  This can be daunting stuff if you're
unfamiliar with it, but it's doable.

It's probably more work than designing phase control dimmers, which was
one of my first PIC projects.

Good luck!
