Hi Radek,

To animate your snowflakes you need to modify the amount you move each one 
based upon the 'clock' variable. The following source adds a vector to the 
position of each flake to produce a very simple animation. It checks to make 
sure the flake hasn't dropped out of the bottom of the box and, if it has, 
it moves it back to the top of the box, positioning it so that it will 
produce a seamless animation cycle when rendered with the command line 
settings of   '+kfi1 +kff30 +kc'.

A couple of notes on protocol: I think it would have been better to post 
this question on the 'povray.animations' newsgroup as 
'povray.binaries.animations' is more for example animation files and stuff. 
CAPITALISATION is sort of like shouting and is more commonly used on 
newsgroups where questions don't get answered.

#declare FallVector = <-0.1,-1,-0.1>;

#declare ile=1000;

  <0,0,0>,
  .1 pigment
  { color White }
}

#while
     (licz <ile)
        #declare los=VRand_In_Box(PtA, PtB, nasio);
        #declare los = los+FallVector*clock*35;
        #if (los.y<=0) #declare los = los-FallVector*35; #end
        object { platek translate los }
        #declare licz=licz+1;
#end
