I want to do this for my kids to make reading exciting - for every stair, we'll read the book. Staircase to Knowledge by sungazing: Stairway to the reading room at The Magic House, St. Louis Children's Museum in Kirkwood, MO
add wood wallpaper to the kick plates of the stairs. Those rolls are expensive but you would only need one. Not practical with white treads though, it will be stuffed up from black shoe soles in no time.
