An artist of Czech Roman TycCzech has amazed all the vehicles and people along the zebra crossing of road. Usually vehicles may stopped on red lights and people go through while green But an amazing art work done by  Roman Tyc (née David Hons), member of the guerilla art group Ztohoven, replaced 48 traffic lights in Prague by amending the normal red and green figures to show them in situations such as drinking, urinating and being hanged, as well as more benign ones such as a man walking his dog. The procedure of such an art was embraced by the public as great fun (as well as awarded top prize at Austria’s Sidewalk Cinema Festival in Vienna that year) but, naturally, not so much by the authorities.
