Heat sensitive wallpaper/Тапет, чувствителен на топлина

I only just now discovered this (though аpparently it's several-years-old news)... a wallpaper that is sensitive to heat and changes pattern! Made by the Chinese designer Shi Yuan who lives in the UK. I am impressed!

Впечатляващо! Тапет, който си променя шарката от топлина!
