resynth
resynthesis is the process of taking a source texture and creating similar (oft tiling) textures based on it.
resynth is a C rewrite of the original resynthesizer by Paul Harrison. it does not require GIMP to function; just feed it image paths and it will save copies. however, this program lacks the patching (masking) and texture transfer abilities of the original plugin.
resynth produces tiling images like those seen here.

usage:
-a --autism
sensitivity to outliers
range: [0,256]; default: 32
-N --neighbors
points to use when sampling
range: [0,1024]; default: 29
-r --radius
square neighborhood, always odd
range: [0,32]; default: [n/a]
-R --circle-radius
circle neighborhood radius
range: [1,128]; default: [n/a]
-M --tries
random points added to candidates
range: [0,65536]; default: 192
-p --polish
extra iterations
range: [0,9]; default: 0
-m --magic
magic constant, affects iterations
range: [0,255]; default: 192
-s --scale
output size multiplier; negative values set width and height
range: [-8192,32]; default: 1
-S --seed
initial RNG value
default: 0 [time(0)]
{files...}
image files to open, resynthesize, and save as {filename}.resynth.png
required default: [none]
apologies for the radius, circle-radius, and polish parameters.
they should be properly described or removed.
