This script simulates the cut-off of the first picture of a film roll of cheap cameras like Lomo. Role model was this picture from flickr. Copy it into the scripts folder from GIMP, you will find it then under Filters -> Generic -> Photo Border.
Unfortunately without FFTW3 so far (because I do not have it on my system yet), and thus slow.
The attachment is meant to be extracted into the GIMP program directory, if you want to place it elsewhere, just drop the executable to the right place. Translations for Italian, Japanese and Russian are included.
Creates a Lightsaber effect.
To successfully create the effect, you need a black layer with a white line (roughly 2-10 pixels wide)
The layer must be selected.

This script automates many of the steps in MarvinX's fantastic "Make a Planet" tutorial, with a couple of added features. There is an atmospheric haze around the planet, and there are stars on the background layer. This script does not do the IWarp step. I leave that to the individual user to make wherever they want.. Everything else is in here.
Lomo-Gimp tries to give your digital pictures the warmth of those taken by an old rangefinder analog camera. Think of it as a Kodak Instamatic or a Lomo Holga faking effect. It enhances contrast and saturation, and applies a light and a dark overlay, trying to emulate incorrectness in exposition. Please note this does nothing to emulate the chromatic aberration peculiar in pictures taken using a real Lomo.
This script converts color images to B&W using channel mixer settings,
which simulate the use of color filters in B&W photography. It allows to choose many predefined filters and set their intensity. Previously posted to old registry in July 2006, now updated to work with GIMP 2.4. Avoid setting intensity to 1, besause it totally filters one of RGB channels and increases noise.
The code still have some accuracy bugs when compaired with its sdlBasic version, since i were getting some problems when recoding it to Python-Gimp.
The script converts a rgb picture into msx1 (also colecovision and sega sg1000) display limitations, which have a predefined palette, and a maximum of 2 colours in each 8x1 pixels cell, trying to provide this cell as the most close as possible from their rgb original.
As well, the code is a bit slow (a 320x240 picture can take around 1 minute on a 2ghz dualcore computer) since it processes pixel by pixel.
