You've seen those plastic envelopes with layers of two different liquids in them, where pressing the envelope makes the liquids squish interestingly around each other, right? (So stipulated.) Cafe Interiors Liquifloor works on the same principle: made of Class 1 PVC filled with silver trace or chromatic fluids the floor literally changes as you walk across it. You can even write (very temporary) messages, which could be a good way to ask someone something that you wouldn't want inscribed permanently. Cafe Interiors is the same company that achieved notoriety a bit back for designing urinals that look like lipsticked mouths.
