Here's an animation preset to get you started. I didn't animate the= fractal, but I didn't know what kind of motion/evolution you wanted.

Honestly my first approach would not be particular, but a= series of stacked shape layers, each with animated fractal noise scaled= really small on both alpha and color channels - this way you get individua= l control of colors, independent animation for each color (not tied to colo= rama map) and then parent it all to a null for overall animation. Mettle= Freeform pro could come in very handy for shaping the overall forms in = real time as well. =20

Particular could definitely work, but you may find yourself with some= very particular challenges when doing something like this.

Pun definitely intended.

I=E2=80=99ve followed the same general direction as you sugg= est Chris but used Particular to generate the basic movement with a Mosaic= preset on top. The preset was a great start point as it uses Fractal noise= , Mosaic, Median and Tri-Tone which is perfect as I have a palette of 3 = colours. I then added posterise time onto an adjustment layer for the whole= comp. =20

Much easier to create than I had imagined. 

Cheers.

So:

1) Base pre comp with the main elements
2) Grunge version
3) Add mosaic effect and posterise time
4) Bender / bend it / polar coordinates
5) Colourama

Have fun,

Hi,=20

I think I vaguely remember this coming up once before on = here. I need to create and animate a Doppler radar weather type  = graphic. Similar to this:=20


I need to be able to control its centre point and also the positi= on of colours. The centre of the 'storm' would move between predetermi= ned points over time. =20

Feels like a job for Particular but I'm unsure of the = most efficient way of going about it. I have 27 different positions for = the 'storm' to move between in a minute so ideally the only manual key fram= es I'll be pulling will be positional. 

Suggestions for start points appreciated.=20

Thanks.
