I really liked the idea of this when I read it on Daniel Street's blog and I enjoy the pictures so far. But I think that when there is only one main thrust given that they loose some of the immersive qualities that the 1000 word books have with their full scenes with many objects. For instance the image for εἰς τὸ πλοῖον could have words also describing say the dock (which I have no clue what the Greek would be) or the people themselves, ANDRA, GUNH, TEKNA, ANQRWPOI etc. or their clothes etc.
I put together an image more along these lines. I would actually like to do more of them but my vocabulary is so lacking that even this simple picture had to be done with the aid of a 19th century "Greek Vocabulary for Young Boys" systematically ordered.
