Imagination! What a wonderful invention imagination is. You know, if I were going to invent something, I think that's what I would go with. Why, with imagination, one can go places where pure logic just won't take you. Aren't we lucky as humans to have been blessed with the ability to imagine ourselves creative? Did you know that a Bumble Bee cannot fly? Its true. The Bumble Bee's body is much too large for his tiny little wings to carry him. Fortunately, no one has apparently spoiled the fun by informing the clever Bumble Bee, so he flies, anyway.
We are like that. Humans have the wonderful ability to see things for what they can be, not necessarily for what they are. Take, for instance, logs. Let's say you have three log pieces of different widths, but close to the same size. Paint each of those three log pieces white. Let dry. Then, on the bottom one, use a softened blue color to paint the effect of snow. Paint a black spot, as if it were coal, right in the center.
