I've googled intarsia/fair isle knit charts and really not a lot of results come up.
I'm not looking for anything in particular. So please post any sites you know that have charts/patterns.
There are lots of charts on Ravelry and Knitting Pattern Central. maybe just look for charts of a specific thing like flower. I know you're not looking for anything, but it really helps if you narrow it down.
For instance - http://www.ravelry.com/patterns/search#sort=best&craft=knitting&query=Animal%20chartshttp://www.ravelry.com/patterns/search#craft=knitting&query=Flower%20charts&page=1&view=captioned_thumbs&sort=besthttp://www.ravelry.com/patterns/search#craft=knitting&query=Sheep%20charts&page=1&view=captioned_thumbs&sort=best
DROPS has quite a few, albeit incorporated in different garments: http://www.garnstudio.com/lang/en/kategori_oversikt.php
You can search for fair isle and stranded and see if you find something.
