ブライアン・メイさんのインスタグラム写真 - (ブライアン・メイInstagram)「Icosahedron ! This 20-sided polyhedron is one of Nature’s (only) 5 regular solids. I’ve put the whole set on swipe position number 4. This particular giant internally lit icosahedron is made by artist Anthony James. The internal reflections make a fantastic 3-D tracery inside the space it occupies, which seem to stretch to infinity. Swipe for 3 parallel 3-D views, and then the key to regular polyhedra, and the gallery, then the cross-eyed views. Yes, I’m feeling geeky tonight. Or maybe this stuff is a convenient escape from the difficult stuff of real life. Thanks to the Opera Gallery in London - where you can see this piece today. 💥💥💥💥 Why do I have all this stuff in my head, you ask ? I was fascinated by solid geometry when I was a kid - and I made these regular solid objects as Christmas decorations. I’m sure I still have them somewhere ... Bri.
