You know how annoying it is when you want to pin up a photo or a poster on your wall but you don’t want to ruin it by putting a hole in it? Mark Weiser designed Pon as an alternative and it’s pretty clever. Pon takes the puncture out of the push pin and saves your sacred items from the usual holes that hanging brings. The circular coil lets you slide your item in for easy hanging. The right amount of spirals means it fully grips without crumpling your object.
