i liked the kiss from White.
so here is the image, and the script (put it in a prim):

default
{
state_entry()
{
llSetTextureAnim( ANIM_ON | LOOP, ALL_SIDES, 6, 4, 0.0, 64.0, 10.0 );
}

touch_start(integer total_number)
{
llSay(0, "Touched.";
}
}


-------------------------
Put it i a prim and enjoy
