It’s a bit out on a limb, but well worth the effort to get there. You’ve never seen anything quite like the Institut du Monde Arabe in Paris. A stone’s throw from Jussieu metro station, its south facade is a showstopper. Thirty thousand metallic apertures form walls and windows that react to the sunlight all day long, dilating or contracting to let only a gentle light sift through to the inside world. It’s free to enter, so I went straight to the 9th floor restaurant and nabbed a window seat,  calmly sipping mint tea and watching the apertures whirr and mesh into position every few minutes. Shapes morphed, patterns emerged, just like a kaleidoscope. What an innovative way to recreate the beautiful arabesques that we associate with the region.
