Homer Simpson multicolor

I'm playing around with multicolor print while I'm waiting for the multimaterial upgrade for my prusa. I printed this with manual filament change.

I have an Original Prusa i3 mk2 and use slic3r. I don't know if M600 works on other printers or how to slice it in other slicers :)

Video of how I sliced it in slic3r
