Monthchunks
by Justin Watt on WordPress.org

This is how Monthchunks looks with the Twenty Eleven theme. You can see here that 4 years of archives (eventually 48 links) take up less than 200 vertical pixels of precious sidebar real estate. Note that if you're browsing a monthly archive page, that month's number is emboldened, but not linked. If you hover over the link for any month, you'll see the localized month name and year as a tooltip.
Display monthly archives by year with links to each month in the following compact format:
2012
1 2 3 4 5 6 7 8 9
2011
1 2 3 4 5 6 7 8 9 10 11 12
2010
6 7 8 9 10 11 12
Serves as a drop in replacement for wp_get_archives( array( 'type' => 'monthly' ) );.
