Just for giggles I ported gnuplot to the DR800. The plots are actually really beautiful, but the program is a bit of a PITA to use right now. Latest version is gnuplot-4.4.0-dr-2010-04-28.

BUGS:
When the plot window closes, it closes the keyboard with it, and gnuplot doesn't know what happened. Press the page bar (hit enter) to redisplay the keyboard.

In spite of this, it is usable. Also in the box is rxvt, erkeyman. Uses wxGTK, which was a trivial port.

Just extract to your SD card and run. Type in "splot x**2+y" for an example graph. You will be blown away by how beautiful graphs are on eInk. I don't know whether it has any real use, but it's really, really pretty. Type "quit" to quit (if you don't do this, it'll happily float along in the background, which is no good :P )

EDIT 2010-04-23: Later the same day, updated to refresh less often.
EDIT 2010-04-28: Lots of fixes now that I have a much keener grasp of how the iRex works.
