Walking in the '2-way Mirror Labyrinth' at Chiswick Park by Danish contemporary artist and sculptor Jeppe Hein. It's made of 2 rings of high-polished steel pillars (super mirror) that give sort of optical illusion. Jeppe Hein said that mirror has the ability to create various visual, often illusionary effects, to open up, broaden or close a room thus establishing a dialogue between spatiality and people entering the space. Furthermore, artworks with mirrors provide viewers the opportunity for playful interaction and extraordinary reception of the surrounding space. It was fun!
