In case of use to anyone, I made a couple of movies of the linear transfer function evolution from high to low redshift:

Adiabatic mode:

CDM Isocurvature mode:

http://cosmologist.info/notes/transfer_evolve_iso.avi

Red photons, Blue CDM, Green Baryons, all synchronous gauge, initial conditions are unit comoving curvature perturbation and unit CDM density perturbation respectively. For adiabtic I plotted the absolute value, for isocurvature negative are dashed.
