For the seventh summer, I’ll be spotlighting little aspects of life here that I love. To see the previous Valentines, click the Valentine tag at the end of the post.

Grimanesa Amorós’s “Terrarium” at 54 N. Moore is a total delight, and you know I’m tickled by the Dan Flavin installation at 5 Worth. But for my (hypothetical, alas) money, no Tribeca lobby beats 140 Franklin, where architect Aldo Andreoli commissioned murals from Sol LeWitt when the building was converted in 2000. (Thanks to Andreoli for sharing the photos.)
