Indexhibit is a CMS for portfolios that is fairly easy to modify and write plugins for.
They have recently come out with a version 2.
I'd like a theme which :
-uses masonry to show the projects ([url removed, login to view])
-has a horizontal menu on top with 4 columns ( [url removed, login to view] )
