Another artist I really like: Andrea Zittel. Her work explores the boundaries between art and design, modernism, minimalism, and manufactured personalization. I'd love to see what kind of baby/kid environments she'd come up with.
She has also been making clothes for years. I just found this beautiful cap she knitted for an artist friend's baby.
Meanwhile, that artist, Austin Thomas, made some great chairs, including a kid-sized chair, inspired by Thoreau's explanation of his chairs at Walden Pond: "I had three chairs in my house; one for solitude, two for friendship, three for society."
Or three for family, for that matter. The two were in a show about weather earlier this year, called "Out of the Blue."
