Good online photoshop tutorials

I'm trying to better my photoshop skills and am looking for good, free, online tutorials that aren't just "Oh, this is how you remove red eye... and this is how you pick a color"

just play around w/ it
you can learn a lot by saying hey i wanna do this
lets try doing this and this and this

http://www.ps-workshop.net is a good one though if you suck at playing around with shit
