How to know the theme name of a wordpress blog?

I visit http://ltty.wordpress.com/ and want to know the theme name (so that I can use 🙂 for my blog). How can I get it?

This method isn’t always fireproof, but you can often look at the source code (right click on white space in the blog), and look for the word “themes.” For instance, in the case of ltty.wordpress.com, this line appears:

<link rel="stylesheet" href="http://s2.wp.com/wp-content/themes/pub/inove/style.css?m=1285721595g" type="text/css" media="screen" />

The theme is “inove.” A quick Google Search reveals this source:
