Terry King sells a great I2C dislpay, both 2 and 4 line. You can see them here:
He's also a good technical guy and has lots of worthwhile tutorials on his site. Use the link above to see the display, then click on the software examples link to see some tutorial info.

That particular vendor has different sizes and orientations of the 1602
displays - even in the same color, be it black on white, white on black,
white on blue, ...
As to I2C, I searched for those and the only serial that came up were 3
and 4 wire SPI. I didn't see any I2C, but you can get a PCF8574 board
to convert the standard parallel to I2C. The I2C displays I bought just
have that board attached to it and they work fine.
