The exhibition was over on the date of 17th January 2010 and I actually visited in National Science Center during last year with my daddy. Visitors were not allow to take photo but I still couldn't help myself to grab some pictures unnoticed by the others and I didn't see any CCTV. That's actually a lot but I will just post some of my favourite ones.
