I haven't seen this announced here yet: on AdaCore's blog there's a
very nice article by Jorge Real from the Universitat Politècnica de
València, describing a pendulum-like device that creates the illusion
of text floating in the air!

See: <http://blog.adacore.com/writing-on-air>.

See this device in action at the upcoming Ada-Europe 2017 conference,
mid-June in Vienna, Austria!

Information on the co-located tutorials and workshop is already online,
and registration is open.  Information on the full program will be
added to the conference web site shortly.
