Displair

The Displair projects images onto sheets of water droplets suspended in air, giving the illusion of a hologram.

In July of that year he chose the "Displair" name for both the product and the company as a portmanteau of the English words "display" and "air".

[1] The company subsequently obtained investment for further development of the prototype, technology licensing, and small-scale commercial production.

[3] The Displair device projects still and moving images onto a "screenless" display consisting of cold stable air flow containing particles of water produced by a cavitation method.

These particles are small enough not to leave traces of moisture, and their surface tension high enough to maintain stability after contact with physical objects and wind.
