The installation called Of the Now by Nick Bednarz gives wings to anyone who steps into the human outline in the center. If you move on, the wings disappear again. There isn’t much hi tech involved (apparently flash and a light barrier), but the idea is still enchanting. Especially if you don’t know the installation yet and step unsuspectingly into the outline, the effect is probably verrry cool. 🙂
I think it would be even cooler if the wings could follow you around. ^_^
P.S.: The video shows a test projection which was not yet working automatically.
