G'MIC (GREYC's Magic Image Converter) is a tool that comes with a lot (more than 190) of pre-defined image filters and effects for GIMP and is available for Window, Linux and Mac OSX.
The G'MIC Sourceforge page offers .deb files for download, but because new G'MIC versions are released very frequently, it's a good idea to use a PPA to stay up to date with the latest versions in Ubuntu. Roberto @ LFFL has created such a PPA so you can easily stay up to date with the latest G'MIC for Ubuntu 10.04 Lucid Lynx and 10.10 Maverick Meerkat.
Add the PPA and install G'MIC for GIMP in Ubuntu using the following commands:
sudo add-apt-repository ppa:ferramroberto/gimp sudo apt-get update sudo apt-get install gmic gimp-gmic
G'MIC is very easy to use! You don't need any experience to apply some cool effects to your photos. Simply select a photo, run G'MIC and apply an effect. That's all!
To use G'MIC once installed, open a photo in GIMP and go to Filters > G'MIC and a dialog will pop-up where you can select the effect you want to apply. Each effect is of course customizable and you can see a live preview in the G'MIC window.
For tutorials and help, you can visit the G'MIC group on Flickr.
