There is a fastICA library for R (a free statistical analysis
environment) which does ICA and projection pursuit - see
http://cran.r-project.org/src/contrib/PACKAGES.html#fastICA

If you want to access it from Python, try Walter Moreira's excellent RPy
module (see http://rpy.sf.net) which embeds R within your Python
interpreter and provides an incredibly smooth interface between the two
(including the ability to directly pass NumPy arrays to and from R).
