Doormats can beckon visitors into the house with a hearty "Welcome" printed on their surface. But the fact that these mats display the same message as people leave is, frankly, nonsensical. To remedy this, doormats should be made with angled fibers, printed in the method described in the link. When approaching the door, the mat would read the usual "Welcome"; but if viewed while exiting, the mat would display a more appropriate "Goodbye", or a blunt "Get Out".

The mat should say "Welcome" except for a tiny fraction of a second as you approach it, when the mat will display a subversive lenticular subliminal message.

You could make the mat out of a series of adjacent triangular prisms (i.e. a triangular wave in cross section). The person arriving sees the image/text displayed on the right-facing prism faces, while the person leaving sees the image/text on the left-facing prism faces. I'll link to an illustration shortly.

Oh. So not doormats made out of lentils?

No, [norm], that idea's bean and gone ...

We would like a mat that says "Resistance is Futile" in one direction, and "You will be Assimilated" in the other.

Please.

Fallen victim to indecision once again, [IT]. You can't hover on the threshold forever.

You'll wonder why you ever hesitated ...
