Feel like creating them by hand ??
If so try the following in FRHED http://www.tu-darmstadt.de/~rkibria (Win32
only)
Create a new file that is x*y*z + 6 bytes in length (use the append feature;
extra 6 bytes are for dimensions)
(File->New, Edit->Append)

With the cursor in the first byte enter an unsigned decimal value of word
length that is x
(Home key, Edit->Enter decimal value)
Do the same on the 3rd and 5th bytes for the y and z dimensions

On every byte after the 6th (not-including) add a byte length number (0-255),
which will be the density for that voxel
The x, y and z  positions (1 based indexes) are calculated somehow as follows,
where p = position in the file, a = p - 6, xx,yy&zz are the dimensions of the
volume and floor is a func that returns the next integer below its input
z = floor(p / (xx*yy)) + 1
x = (p mod (xx*yy) ) mod xx
y = floor((p mod (xx*yy) ) / yy)
I think these are right - Anyone else know
