#JapanAirlineEventInteractionDesigners will probably be very satisfied. After getting inspired by the exhibition, you can try out your own designs using the provided pens on the interactive display, which was impressive. If you are a student and have financial difficulties, admission is free from 6pm on Saturday and I think it was until 9pm, but the Guggenheim Saturday Donation Admission next door is from 5:30pm to 7:30pm, so I think it would be good to go there first and then go straight to Cooper Hewitt to see it :-)
