I’ve posted a few examples of street art at Conflusions but not many where the image appears to pop up rather than drop down into a hole. This fine piece of art by Manfred Stader and Edgar Müller does just that.
Using LED strobe lighting the drops in this fountain can be slowed down or stopped. You can even interact with them in real time.

This picture was created by the Hungarian artist István Orosz.
