Pool ideas

Hey guys!
I am looking into building an inground pool and was thinking of using ICF Blocks to form the parimiter of the pool and using a vinyl liner. I would use solid concrete but in my area concrete always cracks and i think would not be a good choice.
I was wondering if anyone else has done this and if there is some where I can find more info or (even better some photos) of this type of instilation.
Thanks for your help.
