I found that I couldn't drag the sample images into the box, but dragging from my file system did the trick.

Still failed miserably when detecting the faces though (and I was even using one of their test images).

Aside from the earlier mention of 'I want to just let my cat into the house to the exclusion of others' I think it's interesting because if you're not in the computer vision world, you don't see a ton of stories or demos about detecting things other than human faces in pictures.

Some unmanned spray bottles hooked to cameras would be useful for some mice I know.

Or malicious pups.
