You need an IDL licence to use these routines:

• This routine shows 3D movie-like simulations of stellar pulsations in an IDL window, for the purpose of outreach. It can be used to show what different spherical harmonics look like: IDL routine visualise_p_mode.pro

• This routine makes 3D movie-like simulations of stellar pulsations and stores it in a file called “movie.mpg”, for the purpose of outreach. It can be used  to show what different spherical harmonics look like: IDL routine visualise_p_mode_mpeg.pro

• IDL helioseismic inversion program (using widgets) (Christensen-Dalsgaard et al, 1992)
