Every Friday in February, for three hours (18h. - 21h.), the Leopold Museum in the Museums Quartier of Vienna lets you decide how much you want to pay for the visit. The normal price is 9 Euro. This museum owns the biggest Schiele collection in the world.

And another one : the MAK (Austrian Museum of Applied Arts) opens its doors free-of-charge, gratis, every Saturday from 10:00 am until 18:00 pm., until the end of the year. Some of its best collections are those of the Viennese Jugendstil.
