I've also seen challenge systems where they present you with a small set of images and ask you to select one with a particular property (looks like a tennis racquet, shaped like a square, etc). While simple to solve for most humans -- assuming they can read the language -- they would be difficult to solve by automated means. You can also magnify them for visually impaired or speak what they are on rollover/hover, and don't require any typing. They can make cultural assumptions (not everyone will know what a tennis racquet looks like, for instance), so the images might have to be selected carefully.
