If you enjoyed our interactive billboard post last month about the British Airways outdoor billboard that tracked airplanes overhead, you’re going to really like our next find.

This time it’s a fantasy experience available to anyone who steps onto a marked spot in the middle of Victoria Station. (London’s a happening place for billboard experimentation.) Once you’re there, a holographic angel drops down from heaven and lands beside you. You can’t see her in real space, but you and she are plainly visible on a screen that everybody else in the station can see, and you are free to interact anyway you please. Some people get quite…frisky.

What would you do if you encountered an angel?
