A premiere example of object as form and function. This genius idea by Le Corbeille of creating formed teacup 'handles' from sugar, adds a touch of sweetness, both figuratively and literally. Haven't been able to find them in the US, but you can get them here.
How clever is this? Handles made of sugar, that you can simply add to your coffee or tea. Hopefully the cup's not too hot to handle, though.
