I came across an article about someone who converted an old Macintosh SE computer case into a toilet paper holder. He first cleaned and gutted what was left of it. After applying new white paint to the outside, and silver to the inside; he used super glue to attach a small toilet paper holder. To finish, he added a roll of toilet paper and affixed a plastic binder cover to replace the missing screen. He affectionately named the holder iWipe.
To complement the iWipe, an iToilet is necessary. Here, two guys picked up a discarded toilet, spray painted it silver, matching an iMac and continued to install computer parts; turning an old toilet into a functional computer.
Check out the entire process from beginning to end:
