Wow! I'm completely blown away!
I've never done multicolor printing, and those "bruteforce" wiping towers look bad, so never even tried doing it.
But this, so simple yet does the trick.
Looked around a bit and saw three nice powerful hints around the diamond. My guess: Retract plus standby temperature?

My guess is your simply calculating when the next color is needed and you have worked out how long it takes for a color change to actually start coming out the hotend. You then just switch color ahead of time in the gcode (some tweaks of the gcode are probably needed to get just the right cut location)
This is something I have wanted to try for ages...

Have you written a post processing script or do you alter the gcode manually? I'm sure it would only be necessary for the perimeters and only the final layer ( eg, for the flag in the video ) needs to be perfect.

What are your plans with this PP-script? Selling it to the highest bidder?

As it stands, the script gets the job done but it ain't pretty and any professional programmer would probably laugh at it (or cry).

I was so impressed by deckingman's work on this and his results that I intend to add this facility to RepRapFirmware, so that you can print the gcode directly without pre-processing it.

Hi,
Congratulations on the good work. Do you think this could also be used to print with dissolvable supports?

Thank you!
From what I understand is that it might be worthwhile to investigate the influence of the shape of the "melting chamber" on the result? Could it be that even the entry angle of the filament into the melting chamber has an influence? Like what would happen if that entry is off-center making it whirl more? Just thinking out loud here
