These Java applets for viewing 2D+ images of cuneiform tablets and for
rendering Unicode cuneiform text may be of interest to some:

At least Java 1.4.2 and Safari 1.2.3 are required for viewing on Mac OS X.
These proof-of-concept technology demonstrations are just a peek at some
of the exciting results emerging from the research and development
efforts of the Digital Hammurabi Project and the Initiative for Cuneiform
Encoding.
I was able to get an 8-fold increase in drawing speed by doing the
following optimizations (taken from the source comments):
// I sped the image filtering up 8-fold by doing the following:
// (Speeds come from running on my 17 inch Mac laptop, 1gb RAM, Mac OS X
10.3.6, nVidia GeForce4 MX w/ 64mb RAM)
// Stage 1 = 4 fps: used getRGB() & setRGB() with no direct access to
pixel buffers
// Stage 2 = 16 fps: switched to direct pixel buffers, but still using
Java RescaleOp() for setting brightness
// Stage 3 = 21 fps: replaced Java RescaleOp() with my
CalculateBrightness() method
// Stage 4 = 33 fps: switched BufferedImage from int to byte array, thus
eliminating all the bit shifting to get at RGB components;
// inlined almost all code that was in other functions -
CalculateShading(), etc., plus all 24 Math.min & Math.max calls;
// now checking for background pixels and doing no processing on them.
But even with all of this, the frame rates are much higher on a 2.4 ghz
Windows XP machine. (I haven't profiled it yet but I would guess that it
is 3X times.)
