I reckon he got the idea from our LiDU logo (see left).
Out of interest, and thinking about Helen's earlier comment about kids searching for images rather than documents, I was wondering if there is an application one can use to upload an image and get information about its provenance, eg: in case of the above, who the painter was, when it was done etc.
Someone asked the same Q on Yahoo Answers a year ago and got recommended this: http://tineye.com/login
It still exists but you have to register to use it, and I've already been distracted from this really interesting consultants' contract I'm supposed to be drafting quite long enough!
