To add, we discussed this at work this week, and someone tried cutting the example on our laser printer. Broke when trying to expand it, though.
What material?
Slightly better. The text promises "allow it to morph into 3D shapes", whereas the gifs only show fairly trivial 2D morphing. What one would imagine is "take a sheet of paper and turn it into a 3D flower", but what we get is "take a sheet of paper and turn it into a deformed grid".
