I went to the Triennial on Saturday, and, surprisingly I have very little to say. Except for please go see it---there are no words. Three floors of the Cooper-Hewitt are literally covered in "experimental designs and emerging ideas" from wall to wall. There is something for everyone and it seems that the designers featured are pulling out the stops to bring us the brightest and the best.
The only downside is that you would think that an exhibit about design would attempt to grab the eye and flow a bit better. It can be a little stagnant at times...especially at the Ipod display...but I still think it's worth it.
I wouldn't want to ruin anything but definitely remember to #1: look up, there's awesome things to see on the ceiling, #2: bring some handi-wipes, your fingers will be covered in chalk, #3: no pictures, please! so if you know how to turn the flash off on your camera phone, use that instead when no one is looking.
