What are great examples of products that turn digital interactions, quickly, into material results?

Look for great restaurants around you, order something, and it is then delivered to you. Eat. ;)

This would be an amazing "digital interaction to material satisfaction" story, if it was operational. We can look forward to it though... :)

Turns your stl file into a visible 3D product that ships right to your door. ;-)

Pretty fun to quickly send something cool to someone on the same day.
