I have been seeing the term "tchotchke" used a lot lately. The new store in SanFranscisco Jett Modern has a whole category of accessories called Tchotchke. The Gold Gnomes by Phillipe Starck are my ultimate tchotchke.

This is the offical dictionary definition:
tchotchke \CHOCH-kuh\, noun: A trinket; ... Tchotchke is from Yiddish tshatshke, "trinket," ultimately of Slavic origin.
