You can do it in gimp, toshop and with the great "violet tone mapper" avaible in the download section, but tou'll need a .igi file.

You can see this tut

But if you want "the indigo render", wait for 60 hours or buy a quad core :lol:

Alternatively avoid white and saturated colors. The light bounces "forever" on white materials, thus the noise.

oh and before you ask next for the black frames around the eyes:
suzanne isn't a solid object - the eyes are separated from the head. you need to close the mesh in order to solve this ;)
(every material, especially transparent or translucent ones, need to be closed volumes for Indigo to get the best correctness :))

After rendering 60 hours, then you can go for another 120, and so life goes on..... 8)

which type of tonemapping are you using?

linear -> increase brightness
reinhard -> increase post scale
camera -> increase expoure? (or ISO and shutter speed?)

the values, you give here (2500 spp) sound quite ok ;) Some scenes will even need far longer
