The portable hole has always been one of my favorite cartoon gags, and as a kid I wished there was actually an ACME company out there selling portable holes so I could slap one down and watch the fun.
But since ACME doesn't exist, and there's no such thing as a portable hole, we'll have to settle for the next best thing- Scott Jarvie's optical illusion Void Rug, which give your home that cartoon feel without the danger.
Scott's rugs look so realistic from the right angle that your guests will cry "hole-y cow!", and they come in both round and rectangular shapes so they look sharp in every room in your home.
