This is GFtbox, revision 3634 of 2011 May 31.

GFtbox is a MATLAB program for interactive and off-line simulation of the biological growth of curved surfaces such as leaves and petals, and diffusion and interaction of substances with such surfaces.

GFtbox requires an installation of MATLAB.  It should be compatible with any version from R2007 onwards, running on Windows, Mac OS, or Linux.

To install GFtbox, download and decompress the zip file, which gives a directory called "GrowthToolbox".  You can place this anywhere you want.  Open MATLAB and cd to this directory.  The command "GFtbox" should then open the program's GUI.

Under GFtbox's Help menu are commands for displaying references to several published papers about the system.

Further information and documentation (very much a work in progress at this point) is available at http://www.uea.ac.uk/cmp/research/cmpbio/Gftbox.
