It is called "green boys" or pissing boys. " It's Two bronze figures peeing into the water. Microprocessors make the top of the trunks of the figures rotate, and the pissing organs move up and down. The stream of water writes quotes of famous inhabitants of Prague. Tourists can program the figures by sending an SMS to the number written near, and the sculpture will begin to write the text of the sent message. And the fountain with its outlines repeats the contour of the Czech Republic.
Fantastic contribution to the challenge as always! Thank you so much and have a great night!
