Sort of like two ideas in one. The first one probably won't go over as well.
- Rainbow Color - Is it possible to select a font where each word you type it become a different color. Ex: The cow fell down and got impregnated. The = red, cow = blue, fell = black, down = gold, and = green, got = red, impregnated = blue.
- Shaded Color - Different shades into the whole post. Let's say you pick blue; you begin your post with the darkest shade of blue and by the time you end it it'll be aqua blue. As you post the color of your words gets lighter and lighter.
