Found via ref:blog:spot, The Creating Passionate Users blog is a fabulously funny and informative blog for trainers, teachers or anyone who instructs. The bloggers are all authors of bestseller Head First books (wickedlysmart.com) --a new brain-friendly series from O'Reilly.

With pointed graphics (love those thought bubbles on the 50's couples!) they are "passionate about the brain and metacognition, most especially--how the brain works and how to exploit it for better learning and memory."
