Chris Coyier published a fantastic tutorial yesterday which uses thumbnail based archives. The tutorial shows you how you can create a page which shows a grid of your featured posts.
The grid shows an excerpt and a thumbnail for each post with the user being taken to the article when they click on it.
The post grid could be used for a variety of different things. For example, you could create a page with your best articles or highlight a specific section of your website.
If you are looking for an interesting and unique way to showcase your articles then I recommend you check it out.
