Baseboard and Shoe installed in a house with rounded corner bead.
Here's some crown molding installed in the same house with the rounded corner bead.
Here's some second story crown installed over a stair well.  
This crown molding was installed on a vaulted ceiling.  A lot of carpenters have serious trouble making the cuts necessary to work with a vaulted ceiling, but I know the secret!  I also cased the windows in the picture.
And finally, here's some chair rail, but instead of installing it on a wall, Mark Warring had me install it as a ceiling application.
