Custhom wallpaper

I'm kicking myself for not having posted about this before. I wandered into the Custhom design base in East London (off Brick Lane) and fell in love with their thermocromatic wallpaper. The pretty designs change to reveal extra details and/or colours when heated so I was insistent that they'd look perfect on a chimney flue! The sciency bit: One layer of ink is printed using thermochromatic ink which is affected by a temperature rise (ie heat from radiators/hot water pipes or strong sunlight) this allows certain areas of the design to temporarily change and reveal hidden images throughout the paper then disappear again as the paper cools to room temperature. Their website doesn't appear to be working at the moment but you can find them on Bouf. They have a couple of standard designs but will work directly with you on an your own concepts too. What an original idea!
