Hi Sergio!

I tried this and it worked the I I think you meant.

--------------------------------------------------------
camera {location <0,2,-2>
        look_at  0}

light_source {<1,1,-1> color rgb<1,1,1>}

#declare RAND1 = seed(12345+(clock*10));

cylinder {0,y,0.25 
          pigment{color rgb <1,0,0>}
          scale <1,0.9 + (0.2 * rand(RAND1)),1> }

--------------------------------------------------------
