Many of the names used by the group's members are puns, some of which (e.g. Roman Tyc, Dan Gerous or Ana Ward) are chosen to work in English as well as Czech.
First event of Ztohoven at all was when they covered the left half of a 20 meter tall pink neon heart by Czech artist Jiří David and installed on Václav Havel's demand on the rooftop of the Prague Castle, the seat of the President.
[citation needed] Everything was cleaned up by subway workers during the next 24 hours, but in the meantime, hundreds of people came to see and witness this event which had no precedent in Czech art history.
On the live morning ČT2 TV show "Panorama", the pre-recorded video was broadcast; it depicted a fictitious atomic explosion with mushroom cloud over the mountains.
This led to the January 2008 announcement that six Ztohoven members would be prosecuted for scaremongering and spreading false information; they faced prison sentences of up to three years.
[2] In December 2007, the Czech National Gallery awarded Ztohoven the NG 333 prize for works unrelated to the "Media Reality" incident; this included CZK 333 000.
Through twelve months they lived under that fictitious identity, participated in elections, traveled abroad, applied for and received a gun license, or even married.
In July 2011 Ztohoven added one cross to the remaining 27 crosses lying on Staroměstské náměstí (Old Town Square in Prague) in order to express a tribute to unjustly neglected Martin Fruwein from Podolí - one of the 28 Czech Lords claimed responsible, and so to be executed for the revolt for Czech ideals - who had apparently committed suicide in the meantime, so on the day of the execution (21 June 1621) only his dead body was decapitated.
During the first minutes people were watching a live broadcast from Congress on Czech TV - targeted deputies staring at their mobiles, twisting heads, searching for the authors of messages in order to confirm the sender.
In November 2012 the group published cell phone numbers of Czech deputies and President as a part of the exhibition Morální reforma (The Moral Reform) in the modern art center DOX, Prague - Holešovice.
[4] On Saturday 19 September 2015, members of Ztohoven stole the presidential flag flying over Prague Castle and replaced it with a flag-sized mock up of a pair of red boxer shorts.
[5] A confusingly backdated blog post on the group website linked to a video of the prank and stated that finally, here was flying the standard of a man who is ashamed of nothing.
The previous week, he added, while in conversation with television political correspondent Václav Moravec, the security arrangements at the Castle had been discussed without regard to the issue of giant red boxer shorts, and had been found wanting.
