We all have our mood swings. Sometimes you just want to let people know that you’re in a shitty mood. For times like those, theres the Universal Doormat. Like the famous “Princess / Old Lady” optical illusion, the message on the mat changes when you change its direction. One angle reads as “Come in”, the other, less polite side, reads “Go away”.

Designed by SUCK UK, the Universal Doormat isn’t available yet, but should be for sale soon according to the site. This is one doormat that could save you the hassle of dealing with unwanted guests on your bad days. And if you don’t have mood swings, its just simply a really cool doormat. — Andrew Dobrow

Optical illusions can be fun. Messing with the human senses is always a good time. But when it comes to our green, the last thing we need is to think it’s in danger. The Micro Bank optical illusion does exactly that. When you put a coin into the slot, the Micro Bank gives the appearance of becoming impossibly narrow at the bottom as the coin slides down the funnel. The coin reappears in the inner box, apparently 75% smaller than its normal size. But don’t fear! This is in fact just an optical illusion. Open up the slot in the back and you’ve got your money, full sized and as good as new. The box itself is 8 x 8 x 12cm so it should fit nicely in your house. Available now for $19.95, or 9.99 euros for you keeping score. — Andrew Dobrow
