Here is a screenshot of my theme admin meta box.
I specially coded a meta box for my theme, so that I can control my theme layout more efficiently. There are custom field settings for post thumbnail, tweetcount button, post banner, add to cart button, view cart button, etc. There is a list of sidebar for me to choose, so that I can have any sidebar I want for that particular post or page!
Anyone interested to know can read up on the tutorial on WordPress Codex. If you want to code a Post Meta Box for your theme, you can always hire me!
