My wife reads food blogs, and found a site with picture of murals made of apples. The use of color makes these seem as impressive as the ice sculptures and sand castles I linked to earlier.
But having lived and taught in a part of the country so poor that using food for art or classroom projects was frowned upon (and elementary school teachers had to buy their own chalk), I do have mixed feeling about how socially acceptable apple murals would be to all people.
(I should warn folks that the last link is to The Toaster's Handbook, a collection of jokes compiled in 1916 for people who need a joke to share before giving a speech. Need I say that some contain language and ideas that we are thankful society has outgrown?)
