Playing Fruit Ninja on thin air

Okay, I lied in the title, it is actually just vapour (which is way more boring). This reporter is playing a game of Fruit Ninja on Displair (at the low low price of only $10,000), this demo shows how bad technology is      shows how expensive a game of Fruit Ninja is    only shows that tablets are much better shows how vapour can be used to have an image projected onto it, thus giving the appearance of playing on thin air.

As you can tell the performance isn't the best due to low response times, it won't be available to consumers (read: peasants) for at least 5 years so hopefully the product will improve by then.
