In an eco-friendly way of portraying Nintendo characters like Princess Peach, check out this creative art work made of recycled bottle caps. This would definitely be a great idea for people who are also bottle cap collectors.
Rather than throw or store them away, put them into good use and bring out the artist in you. Like for this case, the guy behind the Princess Peach Art assigned 26 different color codes to each of the pixels and sets to work. He then hand painted every lid with a dowel rod, followed by the assembling.
