NGsims
We have developed a method of creating statistically-isotropic non-Gaussian maps of CMB temperature fluctuations. The code for creating simulations for both the full sky (using the Healpix pixelisation scheme) and for the flat-sky can be downloaded now.
Code for full sky simulations.The full version of the paper describing this method and the statistical properties of the resulting maps is available here.
A summary of the method with a series of items describing the logical steps taken is available here.
