Dennis Culver has finished his "Bat-Villain-a-Day" marathon, and the finished product can be seen below in tiny form. But go to his Flickr page to check it out full-size. It's awesome, and there's a character key for all the baddies you don't recognize. I like that he did Egghead and King Tut, but my personal favorite is his interpretation of the Joker. That may be the only updating of the character's look that I've ever liked.
But no Blockbuster, dammit!
