How can you not love a big pink dinosaur? I went down to Yerba Buena Center for the Arts to have a second look. This time I took along my neighbors, 4 and 6 years old. They agreed — the dinosaur is cool. The dinosaur is made out of hundreds of recycled pink plastic bottles. The installation is the work of the team of Indian artists Thukral & Tagra. It’s my favorite part of YBCA’s current show The Matter Within: Contemporary Art of India.
