Show post two by two in a division

Hi guys,

I got a small problem on my project.

I need to do a small slider wich shows some post of X category. On each “slide”, I need to show two post and so on.

For the moment, I got this code, but it doesn’t works.

// The Query
query_posts('cat=5');

// Test
$i = 0;

// The Loop
while ( have_posts() ) : the_post();
?>

<div class="box-ticker">
<a href="#"><img class="ticker_texte" src="<?php bloginfo('template_url'); ?>/images/index/img-test.gif" alt=""/></a>
<span class="caption-ticker"><?php echo the_title(); ?></span>
</div>

<?

endwhile;

// Reset Query
wp_reset_query();

?>

What I would like to do is something like this :

-Make the query
-- Create a <div> with an unique ID (mydiv1)
--- Show the first two posts
-- Close <div>
-- Creation a <div> with an unique ID (mydiv2)
--- Show the second two posts
-- Close <div>
- end query

I’m not sure if this is super clear, but is somebody ever felt on a problem like mine? I really need help ??

Thx in advance
