Attached Link: xero-graphics free photoshop plugins

The link above to xero-graphics has downloads of some filter such as "Illustrator" and esp. "Carvagio" which produces results far better than shown in the authors samples. Above is a render with a one-click aplication of Caravagio.

Mike Finn has great Photoshop actions if you are comfortable with using actions. See:
