I just finished the book "Made to Stick " by Chip and Dan Heath (really enjoyed it) and found some great resources on their website.  One in particular is an article entitled, "Making Your Presentation Stick".  They have other great resources like "Making You Stick" for standing out in job interviews and "Teaching That Sticks".  You have to register on their website, but the articles are a quick read and very helpful.  I highly recommend checking it out: http://heathbrothers.com/resources/#mts
