I set one up for a French review, popped it up on the overhead screen and we had a good time with it - I wished I had created more than just one! I'll be looking for more ready made ones that suit me - there are quite a few of them!
Good higher level thinking skills for kids too - remember, they are only seeing the answer within a category and have to figure out what the question is...
