I had a similar problem... Eventually I moved on to GLscene... Though obviously it's probably not at all what you want to do, but it's pretty easy to rotate things there. :-)
obj.rollangle := obj.rollangle + 90; You can use an orthogonal camera if you don't want / need the perspective. You can even let it "slowly" rotate using a cadencer, but let's not jump the gun here.
